Can anyone help me with this?

Constant of proportionality is

Equation is

================================================

Explanation:

The general equation they give is c = rg

Solving for r leads to . We divided both sides by g to get this.

Now pick any point on the diagonal line. I'll pick (3,10)

The graph shows the horizontal axis is g and the vertical axis is c. The point (3,10) means g = 3 and c = 10 pair up together.

Making r to be,

and the equation in the form c = rg would be

175

step-by-step explanation:

2 inches x 10 miles = 200 miles - 3 inches = 175
