Answer:
x = 1
Step-by-step explanation:
(y2 - y1) / (x2 - x1) = m
(x,2)....x1 = x and y1 = 2
(-5,8)...x2 = -5 and y2 = 8
now sub
(8 - 2) / (-5 - x) = -1
6 / (-5 - x) = -1 .....multiply both sides by (-5 - x)
6 = -1(-5 - x)
6 = 5 + x
6 - 5 = x
1 = x
lets check it..
(y2 - y1) / (x2 - x1) = -1
(8 - 2) / (-5 - 1) = -1
6 / -6 = -1
-1 = -1 (correct)...so it checks out
x = 1
