X = -5; since both your X coordinates are at -5, it's a vertical line, and therefore the slope is undefined.

u need y=mx+b and m=(y2-y1)/(x2-x1)

1. label points (-5,1) (-5,-2)
x1 y1 x2 y2
2. calculate m=(-2-1)/(-5-(-5))=-3/0 stop!! stuff/0 => line is x=x value of 2 points

3. answer x=-5

(-5,1) and (-5,2)

m = (2 - 1)/(-5 - (-5))
m = 1/0
m = undefined

ANS : x = -5
