Nostrana [21]

Answer:

y=28.5x

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form y/x=k or y=kx

In this problem

Let

x------> the number of gallons

y------> the number of miles

the relationship between the number of miles and the gallons of gas represent a linear direct variation

The constant of proportionality k is equal to the slope m

m=\frac{465.3}{16.5}= 28.2\frac{miles}{gallon}

therefore

the equation of the linear equation

y=28.5x
