Describe how you would find the constant of proportionality in a graph

To find your constant of proportionality from a graph, follow these steps:

   Find two easy points.    Start with the leftmost point and count how many squares you need to up to get to your second point.    Count how many squares you need to go to the right.    Simplify, and you've found your constant of proportionality.

Its equal to d=7.07in
