studygurl14 · Answer

Use the slope formula. Do you know how?

mathstudent55 · Answer

The rate they are referring to is the slope.
First, use the given points in the graph to find the slope of the graph.
Then find the choice with a higher slope.

mathstudent55 · Answer

In y = mx, m is the slope or rate.
