Question

The speed of an object in space is shown in the graph.

What is the slope of the line?


A.10

B.15

C.20

D.25

Answer 1

B

Explanation:

To find the slope, find the vertical distance and the horizontal distance between the points. Then write the distances as a ratio.

6 - 3 = 3

0.4 - 0.2 = 0.2

The slope is 3/0.2 = 15.
