Question

Imagine that a line on a Cartesian graph is approximately the distance y in feet a person walks in x hours. What does the slope of this line represent?

Answer 1

Slope is the change in y over the change in x. So the slope represents the distance divided by the time.

Distance divided by time is rate -

 

d = r · t

d / t = r
