### Requirements

Two linear equations, with two variables, are presented and students use graphs to solve the system of equations. Students graph the lines and solve the problem using the graphs. This is the fifth of seven activities for teaching and learning linear equations in algebra: Ski Slope; y=mx+b; Points, Intercepts, and Slopes, Oh My!; Linear Word Problems; Solving Systems of Equations by Graphing; Systems of Equations Word Problems Part 1; Systems of Equations Word Problems Part 2.

» Lesson Plan and Student Assessment documents are also available.
