The answer is A based off point slope form
Answer: c) x = 5
<u>Step-by-step explanation:</u>

(-3,7)(9,5)
midpoint formula : (x1 + x2)/2 , (y1 + y1)/2
(-3 + 9)/2 , (7 + 5)/2 = (6/2, 12/2) = (3,6) <==
I don’t know what answers you have but I think it’s 23.4
So the x intercepts are going to be at the places where y = 0 so you can just read that off and get (-2,0) and (3,0). Hope this helps :)
