Do-Now 02-10-2016 On your notes worksheet!!! Graph: 3x + y = 6 m = b =

2
Objective: Solve a system of equations using graphing.

3
Definitions: System of equations: A set of two or more linear equations in the same variables. Solution: An ordered pair of numbers that is a solution to each equation in the system.

4
Checking Solutions: Example: Tell whether the ordered pair is a solution of the system of linear equations 1. x + y = 6Ordered Pair: (5, 1) 2x – y = 9

5
2. y = -x + 2 Ordered Pair: (-1, -5) y = 3x – 2 Checking Solutions: Example: Tell whether the ordered pair is a solution of the system of linear equations

6
Steps to Solving a System of Equations using GRAPHING: A. Graph each equation in the same coordinate plane. B. Estimate the point of intersection. C. Check the point from Step B in each equation.
