Worksheets for Grade 7, Module 1, Lesson 5 (Student Version)

- Students decide whether two quantities are proportional to each other by graphing on a coordinate plane and observing whether the graph is a straight line through the origin.
- Students study examples of quantities that are proportional to each other as well as those that are not.

When two proportional quantities are graphed on a coordinate plane, the points lie on a straight line that passes through the origin.
