Answer:

x = -5

Explanation:

Find the gradient:

  • m = change in y ÷ change in x
  • m = (7 - -7) ÷ (-5 - -5)
  • m = 14 ÷ 0
  • m = 0 - There is no gradient, and it is a vertical line

The equation is x = -5, because in both co-ordinate pairs, the x is -5 - only the y changes

Hope this helps!
