Yolanda is riding her bike. The number of revolutions (turns) her wheels make varies directly with the distance she travels. See the graph below.

How far does Yolanda travel per revolution

What is the slope of the graph

Answer:

Explanation:

The straight line graph is that of the number of revolutions on the vertical axis against distance travelled in feet on the horizontal axis.

Slope = change in the value of y on the vertical axis/ change in the value of x on the horizontal axis

Slope = (y2 - y1)/(x2 - x1)

Slope = (6 - 2)/(24 - 8) = 4/16 = 1/4 revolution per feet.

It means that in 1 feet, Yolanda makes 1/4 revolutions. Therefore, The distance that Yolanda travels per revolution would be

1/(1/4) = 1/0.25 = 4 feet
