Question

Item 4

This graph shows a proportional relationship.

What is the constant of proportionality?

Enter your answer as a decimal in the box.

Answer 1

Explanation:

The constant of proportionality is the same thing as the slope when the y intercept is 0.

y1 = 27.6

y2 = 82.8

x1 =2

x1 = 6

m = (y2 - y1)/(x2 - x1)

m = (82.8 - 27.6)/(6,2)

m = 55.2/4

m = 13.8

The constant of proportionality = 13.8
