What are supplementary lines i’m s confused

Hey!

Supplementary lines are two angles that when added together it equals to 180 degrees.

Example:

Let's say angle a was 60 degrees and angle b was 120 degrees. We add both them together and get 180 degrees in total. So these angles would be supplementary.

Hope This Helped! Good Luck!

y > 1/3x

y < = -x + 4
