This document provides an introduction and overview of linear equations in two variables. It defines linear equations as equations where each term is a constant or the product of a constant and a single variable. Linear equations in two variables can be represented graphically as a straight line on a coordinate plane, where the solution is the point at which the line crosses the x and y axes. The document discusses how to solve systems of two linear equations in two variables and represents different types of linear equations graphically, including lines parallel to the x and y axes.

Linear Algebra may be defined as the form of algebra in which there is a study of different kinds of solutions which are related to linear equations. In order to explain the Linear Algebra, it is important to explain that the title consists of two different terms. The very first term which is important to be considered in the same, is Linear. Linear may be defined as something which is straight. Linear equations can be used for the calculation of the equation in a xy plane where the straight lines has been defined. In addition to this, linear equations can be used to define something which is straight in a three dimensional perspective. Another view of linear equations may be defined as flatness which recognizes the set of points which can be used for giving the description related to the equations which are in a very simple forms. These are the equations which involves the addition and multiplication.
Polynomials And Linear Equation of Two VariablesAnkur Patel
A complete description of polynomials and also various methods to solve the Linear equation of two variables by substitution, cross multiplication and elimination methods.
For polynomials it also contains the description of monomials, binomials etc.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

3. 1. Introduction:
In earlier classes, you have studied linear equation in one variable. Can you write Down a
linear equation in one variable? You may say that 𝑥 + 1 = 0,𝑥 + 2 = 0 and 2𝑦 + 3 = 0 are
examples of linear equation in one variable. You also known That such equations have a
unique (i.e one and only one) solution. And also how to Represent the solution on a number
line. In this chapter, the knowledge of linear equations in one variable shall be recalled and
extended to that of two variables.
“Linear equation is an algebraic equation in which each term is either a constant
or the product of a constant and a single variable. linear equation can have one
are more variable”.
2. Linear Equations:
In y = ax + b, x is called independent variable and y is
called dependent variable. a and b are called constants.
y = 2x + 5 with a = 2 and b = 5, y = -3x + 2 with a = -3 and b = 2,
and y = 4x + - 1 with a = 4 and b = -1 are other examples of linear
equations.
I am thinking of a number. If 1 add 2 to that number, I will get 5. What is the number?
Although it may be fairly easy to guess that the number is 3, you can model the situation
above with a linear equation.
Let x be the number in my mind.
Add 2 to x to get 5.
Adding 2 to x to get 5 means that whatever x is, when I add 2 to x, it has to equal to 5.
The equation is 2 + x = 5
Example:
4. The linear equations in one variable
is an equation which is expressed in the
form of ax+b = 0, where a and b are two
integers, and x is a variable and has only
one solution.
For example, 2x+3=8 is a linear equation
having a single variable in it.
Therefore, this equation has only one
solution,
which is x = 5/2.
And representation of linear
equation in one variable on line
5. An equation is said to be linear equation in two variables if it is written in
the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x
and y, i.e a and b respectively, are not equal to zero.
For example, 10x+4y = 3 and -x+5y = 2
are linear equations in two variables. The solution for such an equation is a pair of
values, one for x and one for y which further makes the two sides of an equation equal
While solving an equation, you must always keep the following points in mind
1. The same number is added to (or Subtracted from) both the sides of equation.
2. You multiply or divide both the sides of equation by the same non-zero numbers
6.
7. 3. Solution of Linear Equations in Two Variables:
The solution of linear equations in two variables, ax+by = c, is a particular point
in the graph, such that when x-coordinate is multiplied by a and y-coordinate is
multiplied by b, then the sum of these two values will be equal to c.
Basically, for linear equation in two variables, there are infinitely many solutions.
Example 1:
In order to find the solution of Linear equation in 2 variables, two equations
should be known to us.
Consider for Example:
5x + 3y = 30
The above equation has two variables namely x and y.
Graphically this equation can be represented by substituting the variables to zero.
The value of x when y=0 is
5x + 3(0) = 30
⇒ x = 6
and the value of y when x = 0 is,
5 (0) + 3y = 30
⇒ y = 10
11. 4.Graph of a Linear Equation in Two Variables:
1.Any linear equation in the standard form ax+by+c=0 has a pair of solutions in
the form (x,y), that can be represented in the coordinate plane.
2.When an equation is represented graphically, it is a straight line that may or may
not cut the coordinate axes
Case-1
1.A linear equation ax+by+c=0 is represented graphically as a straight line.
2.Every point on the line is a solution for the linear equation.
3.Every solution of the linear equation is a point on the line.
12. Example: 1 Draw the graph of x+y=4 in two variable?
Solution:
Scale
X-axis=1unit=1cm
Y-axis=1 unit=1cm
13. Case:2 Lines passing through the origin
1. Certain linear equations exist such that their solution is (0, 0).
Such equations when represented graphically pass through the origin.
2. The coordinate axes namely x-axis and y-axis can be represented as
y=0 and x=0, respectively.
3. The graph of the equation of the form y=kx is a line
which always passes through the origin.
(0,0)
y=kx
origin
18. 5.Equations of Line Parallel to x-axis and y-axis:
1.Linear equations of the form y=b, when represented graphically are lines
parallel to the x-axis and b is the y-coordinate of the points in that line.
2.Linear equations of the form x=a, when represented graphically are lines
parallel to the y-axis and a is the x-coordinate of the points in that line.
x=a Y=b
