Question

If the two points are (9, 260) and (29.5, 530), calculate the slope of the line that runs through them.

A. 13.17

B. 12.25

C. 11.32

D. 10.42

Answer 1

m = rise/run = 270/20.5 = 13.17

Explanation:

Going from (9, 260) to (29.5, 530), we see that the horizontal change (in x) is 20.5 and the vertical change (in y) is 270. Thus, the slope is

m = rise/run = 270/20.5 = 13.17
