Do it like this one.
===============
(2, -8) and (x, 2); slope: -10/3
----
Slope m = diffy/diffx
m = (-8-2)/(2 - x) = -10/3
-10/(2-x) = -10/3
-30 = -10(2-x) = -20 + 10x
10x = -10
x = -1

(x, 7) and
(9, 2) m =%28y%5B1%5D+-+y%5B2%5D%29%2F%28x%5B1%5D+-+x%5B2%5D+%29 = (5)/(x-9) = -9, x+-+9+=+-5%2F9 x = 76/9
m =%28y%5B1%5D+-+y%5B2%5D%29%2F%28x%5B1%5D+-+x%5B2%5D+%29 =+5%2F%28%28-5%2F9%29%29 = -9
