1. Solving System of Equations by Graphing

2. Learning Intention/Success Criteria
LI: We are learning how to solve a system of equations by graphing SC: I know how to -determine if a system of equations has many solution(s) -determine if a system of equations has no solution -determine if a system of equations has one solution -solve system of two linear equations in two unknowns by graphing -read solutions to system of equations off the graph of two functions -graph a linear equation

3. Example 1: Graph the system of equations and find the solution y = -3x + 2 y = 2x – 3
(1, -1)

4. Example 2: Graph the system of equations and find the solution y = ½x – 3 3x + 6y = 2
_______________
No Solution
6y = 3x + 12
___ 6
___ 6
___ 6
y = ½ x + 2
Talking Points:
Use foldable to help (DCMAM)
What are things the students notice about the shapes of the line? Equations of the line?
y = ½x + 2
