1. Warm-Up
Solve the system by graphing.

2. Notes Solving a System of Equations by Graphing
1. Write each equation into slope-intercept form.
What is m and b?
m = move
b = beginning
2. Graph both equations in the same coordinate plane.
3. Find the point of intersection.
4. Check your answer.
- Plug that point into both equations and make sure that it is true for both.
