This Instructional Activity is a part of the Lesson 3, Unit 3, Grade 8. Ask previously identified students to share their graphs and how they chose the scales for their axes. If possible, display several graphs from each question for all to see as students share. Ask students "Which representation makes it more di'cult (and less di'cult) to calculate the constant of proportionality? Why?" and give 1 minute of quiet think time.
