Answer 1

A: 12 feet per revolution; B: 3

Explanation:

A). You can find the feet Teresa travels per revolution by looking at the graph and identifying the y-value of the x-value of 1, which is 12 feet.

B). The slope can be found by using two methods:
`(y - y_(1) )/(x - x_(1) )` or the counting method where you go up and right (or vice versa) until you reach the point you wish for.

Either way, you are supposed to get a slope of 3.

Hope this helped! :D
