Question

The table below shows that the number of miles driven by Francisco is directly proportional to the number of gallons he used.

What is the constant of proportionality between the number of miles driven and the number of gallons used?

Answer 1

Explanation:

Divide the y value by x and that is your constant of proportionality. so: 1002.8/23 = 43.6 mpg; 1656.8/38 = 43.6 mpg; and 1787.6/41 = 43.6 mpg

So the ratios are equivalent and the Constant of Proportionality is 43.6 or K=y/x.
