Answer:
x = -18
Step-by-step explanation:
Well you just have to do the this formula to find the slope
[tex]\frac{y2 - y1}{x2 - x1}[/tex] Plug in
[tex]\frac{5 - 12}{x - -4 }[/tex] = [tex]\frac{-7}{?}[/tex]=[tex]\frac{1}{2}[/tex]
So we know x will have to be a negative to get 1/2
I would think x = -18 because -18 - -4 = -14 so it would look like this
[tex]\frac{5 - 12}{-18 - -4}[/tex] = [tex]\frac{-7}{-14}[/tex] =[tex]\frac{1}{2}[/tex]
When you further simplify -7/-14 you get 1/2
