Determine which ordered pair is not a solution of y= -4 , x -9

(-9,27)
(3,-21)
(5,-28)

This is graphing coordinates.

Please help I've been staring at this for 30 minutes so confused.

All you have to do is plug in the x and y values from the coordinates into the equation. See which ones make sense and fit in and which one doesn't. Does that make any sense? Hope this helps. (=
I know it’s not one of the answer but if you are taking the graphing in the coordinate planes test the answer is (-6, 15)
