Published on 06/09/2008

#### Activity Overview

Students learn to associate the slope of a straight line with a constant rate of change. They also learn to calculate the rate of change from data points on a line, using the correct units. Students also learn to read from a linear graph: the rate of change, the scale of the axes, and the correct units.

#### Before the Activity
