• 2 or more equations occurring at the same time• Solution is an ordered pair (x, y) that solves both equations• Lines will do one of:
1) Intersect – 1 solution2) Parallel – No solution3) Same line – Infinite solutions
3 graphs were from Homework 34 (2 parts to HW 34)
Lesson 4-1: Systems of Linear Equations
Objective:Students will:•Determine whether an ordered pair is solution to a system.•Use a graph to find solutions to systems of equations.
