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.

step-by-step explanation:

at each of the parallel lines adjacent angles are supplementary. the angles have special names identifying their positions with respect to the parallel lines and transversal. they are corresponding angles, alternate interior angles, or alternate exterior angles. an angles is congruent to its matched angle.
