This Instructional Activity is a part of the Lesson 10, Unit 5, Grade 8. In this activity, students work with a graph that clearly cannot be modeled by a single linear function, but pieces of the graph could be reasonably modeled using different linear functions, leading to the introduction of piecewise linear functions. Students find the slopes of their piecewise linear model and interpret them in the context.
