Find the value for x

(x,2) and (-5,8), and m= -1

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
