Explain how to find the constant of proportionality from a graph.

The constant of proportionality is the number that you have to multiply x by to get y. So to find that number based on a graph , you need to look at the different points that are plotted on the graph. Then, you need to write down those points into a x and y table. Once you do that you can look at your numbers and see what the numbers are being multiplied by.

Step-by-step explanation:

Example:

Say my graph had points of

x  y

0 0

1  3

2 6

You have to multiply 3 by 1 to get 3, and 3 by 2 to get 6.
