1. Piecewise Quiz!

2. Warm Up
Solve the system of equations: 3x + 5y = 25 4x + 7y = 34 Think about 4 ways you have learned to solve a system!

3. Solving Systems of non-linear Equations

4. What is a system of equations?
A system of equations is two or more equations grouped together with the same set of unknowns. Ex. 6x + 5y = 3 2x + 9y = 2
Same set of unknowns, x and y.

5. There are multiple ways ways to solve systems of equations.
Today, we will just focus on graphing.
- graphing - substitution - elimination - matrices

6. Check if the following points are solutions to the system
1) (3, 10) 2) (-5, -6)

7. Steps for Solving Systems by Graphing
Solve both equations for y.
Put the equations in your graphing calculator.
Use the INTERSECT tool to find where the equations share a point.
CAUTION: We will be looking at nonlinear systems (not just lines), so there may be more than one solution set.

8. Solving Systems by Graphing
Solve:
y = x x3 - 4y = 12
y - 3x = x – y = 3
