Question

Use (2, 16) and (4,32) to find the constant of proportionality.

The unit rate (constant of proportionality) is
miles
hour
(Simplify your answer

Answer 1

8 miles per hour

Explanation:

First find the slope. The slope is the unit rate/constant of proportionality.

To find slope use the points given and formula y2-y1 / x2-x1

(32-16) / (4-2)

= 16 / 2

= 8

Thus the unit rate is 8 miles per hour.
