  3. 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. • 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 solution • 2) Parallel – No solution • 3) Same line – Infinite solutions 3 graphs were from Homework 34 (2 parts to HW 34)
