This Instructional Activity is a part of the Lesson 14, Unit 3, Grade 8. Given a graph with five lines representing changes in bank account balance over time, students write equations and interpret how points represent solutions. The activity also connects to and contextualizes students' prior understanding of slope and intercepts, and lays the foundation for the coming unit on systems of equations by considering what points of intersection of lines and nonintersecting lines represent.
