PLS HELP IM CONFUSED

Easiest way to solve this is to try plugging in the values from the table into the equations

Let’s try y = x + 4

The first coordinates from the table says
(-9 , -5 )

-5 = -9 + 4
-5 = -5

They match, so y = x + 4 is the right answer. You can try plugging in the other variables if your still uncertain
