This Instructional Activity is a part of the Lesson 12, Unit 2, Grade 7. This activity is intended to help students interpret features of graphs in terms of the proportional relationships they represent. This task highlights two fundamental ideas: The steeper the graph, the greater the constant of proportionality. If the graph represents distance of an object vs. time, the constant of proportionality is the speed of the object.
