Question

What unit rate corresponds to the proportional relationship shown on the graph?

0.33 c.m/s

0.5 c.m/s

0.67 c.m/s

1.5 c.m/s

Answer 1

1.5 cm/s​

Explanation:

The unit rate is the same as the slope.

To find the slope, we use the slope formula:

m=y2-y1/x2-x1

Using our points, we have

m = (9-0)/(6-0) = 9/6 = 3/2 = 1.5 cm/s
