In previous sections, you looked at different ways to represent rates of change using tables and graphs. In this section, you will focus on interpreting the rate of change from a graph.

Match each graph below to a situation that could describe the graph. Drag the tile with the situation next to the correct graph. Click "Submit" to check your work. You can make changes if necessary.

Check Your Answer

Identify points on the line where gridlines intersect, and then use those values for x and y to determine the rate of change.

For proportional situations, how does the rate of change in the graph relate to the situation being described?

Check Your Answer

The rate of change is equal to the scale factor used in the problem situation.
