3. Chapter 8 Systems of Linear Equations and Inequalities
Lesson 8-3b
Solving Systems Equations by Elimination

4. Objective: Students will solve real world word problems involving solving systems of equations using elimination. The students will complete a practice test on sections 8-1 to 8-3 individually in class.

5. Geometry
Find an equation of the line with slope m = -3 and passing through the intersection of the lines x + 6y = 26 and 5x -2y = -15.
4x + 6y = 26
+ 15x - 6y = -45
Write the equation, use y = mx + b.
m = -3 and (x, y) = (-1, 5)
5 = -3(-1) + b
19x = -19
5 = 3 + b
x = -1
b = 2
4(-1) + 6y = 26
m = -3 and b = 2
6y = 30
Answer:
The equation is y = -3x + 2.
y = 5
So, the line with slope m = -3 passes through (-1, 5).

6. Lesson Summary: Objective: Students will solve real world word problems involving solving systems of equations using elimination. The students will complete a practice test on sections 8-1 to 8-3 individually in class.
