This document is a daily lesson log for an 8th grade mathematics class. It outlines the objectives, content, learning procedures, and evaluation for a lesson on linear equations in two variables. The objectives are for students to identify and solve linear equations with two variables and present solutions accurately. The content covers the standard form of these equations and how to find ordered pairs and graph the linear equations. The learning procedures take students through a review, examples of linear equations with two variables, how to solve and graph them, practice problems, and an evaluation.

A. Reviewing
previous lesson
Before we proceed to our next topic let us first
have a review about our previous lesson.
So, what was our previous lesson all about?
What can you say about plotting points?
How many quadrants are there in the Cartesian
Coordinate Plane?

requirements
B. Establishing a
purpose for the
lesson
Without plotting, state the quadrant on which
each point lies?
1. (3,5)
2. (-1,-2)
3. (-6,3)
4. (-4,-3)

C. Presenting
examples/
instances of the
new lesson
I have two balls with me. The red ball is for the
girls and the white ball is for the boys.
I will play a song entitled “Shembot”. While music
is playing, you will pass the ball to one in your
right side. When the music stops you stop passing
the ball. The one who holds the ball will be the
one to answer the question. Using the graph and
the given ordered pairs decodes missing words.

LINEAR EQUATIONIN_ _ _ VARIABLES AND ITS _ _ _ _ _.
Did you enjoy the game?
What was the statement formed?
Exactly! Linear Equation is our topic for the day.
D. Discussing new
concepts and
practicing new
skills
An equation may contain one or more variables. In
our past lesson, we have studied linear equations in
one variable. We learned to find the solutions to each
equations. Let us now consider linear equations in
two variables.
A linear equation in two variables (x&y) has
the standard form
Ax+By=C where A, B, and c are real numbers, and A
and B are not both zero.
Here are some examples of Linear equation in two
variables.
1. 2x + y =2
2. 4x+7y=8
3. X=5-y
Applies
knowledge of
content within
and across
curriculum
teaching areas
E. Developing
Mastery
Give another example of linear equations in two
variables.
Very Good! Those are Examples of linear equations
in two variables.
How to solve and graph linear equation in two
variables?
Example 1
3x-2y=6
Step 1: Find set of ordered pairs.
X -2 0 2
Y
If x=-2, then
3x-2y=6
3(-2)-2y=6
-6-2y=6
-2y=12
Y=-6
(-2,-6)
Can you follow?
Who can solve the ordered pair?
Excellent! And the last ordered pair?
Applies a range
of teaching
strategies to
develop critical
and creative
thinking, as well
as other higher-
order thinking
skills

4. Very Good!
Step 2:
Plot the ordered pair in the Cartesian Plane
Step 3:
Connect the points
Example 2
Y=2x-3
Find the ordered pairs that satisfy the equation.
Who can solve the first ordered pair of x=o?
Very Good! How about if y=0?
Very good! If x=2?
Very Good! Who can graph the equation using the
ordered pairs?
Very good it shows that you understand the lesson.

F. Finding Practical
Applications of
Concepts Construct a table for x and y then graph
1. 2x-y=4
For group 1 use -1 for the value of X
For group 2 x=0
For group 3 x=1
