1. Warm Up # 3
Complete POST – Assessment INDIVIDUALLY!!!!

2. Homework Check

3. Solve by Graphing Worksheet
Work in pairs to complete the Investigation. You will have 20 minutes to complete this.

4. Solving Systems by Graphing

5. Review:
The solution to a system of linear equations is the point where the two lines intersect.

6. Practice – Solve the system by graphing
1) y = 2x + 6
y = 4x + 4
Graphing calculator screen shots on next slide

7. Graphing Calculator

8. 2. Solve by graphing (use your calculator
2. Solve by graphing (use your calculator!!!) Remember: All Equations must be in y=mx+b form!
y – 3x = 10
y = 3x – 4
Hopefully students will notice that the lines have the same slope and not have to graph them to see the solution.

9. 3) Solve by graphing (use your calculator!!!)
3x – 2y = 4
y = -2x + 5

10. 4) Solve by graphing (use your calculator!!!)
-4x + y = 3
x + y = -2

11. 5) )
2x – y = 1
4x – 2y = 2
y = 2x – 3
-4x - 2y = -6
