The document provides information about solving math problems and finding equations of lines from graphs or equations. It discusses the planning process for solving math problems. It also explains how to find the slope, y-intercept, and equation forms like slope-intercept, point-slope, and standard form using two points on a graph or the coefficients in the equation. Methods for determining slope and y-intercepts from different equation forms are provided.

2. Solving process
Plan: We used plan when working on a math
problem a lot because it allows us to know
what to do with the information given to us.
This save us time and confusion later on
when we actually start solving the problem

3. Equations?
Slope intercept form: To find the slope
intercept form equation of a graph, you will
need to have the slope of the line, and the y-
intercept.

4. Equations?
point slope form: To find the point slope form
equation of a line you will need to have the
slope and a point that crosses the line.

5. Equations?
Standard form: to find the standard form of a
line, you will need the x and y intercept of
the line.

6. How to find the slope of a graph
In order to find the slope of a
line you will need to find to
exact points in the line. Once
you have to exact points, you
(27,160)
can find the slope by using the
slope equation.
Y2 - Y1 (6,40)
X2 = X1 answer!
160 - 40 120
=
27, 6 21

7. How to find the slope of an
equation
-To find the slope of a slope
intercept equation, what you 4x + 2 = y
want to do is to look at which
number you are multiplying by
the input. In this case it is the
4.
-To find the slope of a point
slope equation, what you want
y -2 = 3(x - 9)
to do is to look at the number
you are multiplying the x values
by. In this case it will be 3.

8. How to find the slope of an
equation
-To find the slope of a standard
form equation. You will need to 4x + 2y = 20
find the x and y intercept. to do
this you will need to put a zero 4(0) + 2y = 20
(0) on the x to get the y, and on
the y to get the x. Once you put
the zeros, you want to solve for
0 + 2y = 20
x or y depending on which one 2 2
you are doing first. Once you
have the x and y intercept , you
want to plug the numbers in to Answer! Y = (0, 10)
the slope equation
10 - 0 10 X = (5,0)
=
-2
0-5 -5

9. How to find the y-intercept of a
graph?
To find the y intercept
of a line you just have
to look at which point
the line crosses the y
axis

10. How to find the y intercept of
an equation?
To find the y-intercept of a
standard form equation you will 4x + 2y = 20
just need to solve for y. To do
this, you just put a zero at the x 4(0) + 2y = 20
value and solve for
y 0 + 2y = 20
2 2
Y = (0, 10)

11. How to find the y intercept of
an equation?
To find y intercept of a point
slope form equation, you will
need to convert the equation y-1 = 2(x-1)
from point slope form into slope
intercept form. Once you have y-1 = 2x - 2
the slope intercept form
equation, the number you are y = 2x - 3
adding or subtracting will be the
y intercept

12. How to find the y intercept of
an equation?
To find the y intercept of a
slope intercept form equation
all you need to do is to look at
the number you are adding or
subtracting on your equation. if y = 3x + 23
there is nothing adding or
subtracting that means that the
y intercept is (0,0) or the origin.
