Answer:

D. (-5, 30)

Explanation:

If you use a graphing calculator (online graphing calculator - Desmos) you can simply type in the equation of the line (in this case, y = -7x + 5) and the graphing calc will graph that line for you. Then you look at the multiple choice answers and see if those points are on the line or not. In this case, (-5, 30) wasn't. If x were -5, then y would have to be 40, not 30.
