Closing Questions1. How are proportional quantities represented in a graph? They are represented in a graph where the points lie on a straight

line that passes through the origin.

2. What is a common mistake a student might make when deciding whether a graph of two quantities shows that they are proportional to each other? Both graphs can have points that lie on a straight line, but the graph

of the quantities that are proportional to each other also goes through the origin. In addition the graph could go through the origin, but the points do not lie on a straight line.
