Answer: y = -1/4x -5/2
Step-by-step explanation:
4x - y = 4
(rearrange equation)
y = 4x - 4
two lines are perpendicular when both there gradients are timesed together and equal -1
so 4 × ? = -1
so ? = -1/4
so the equation looks a little like this
y = -1/4x + c
but we're not done yet, we need it to find the points (-2,-2), so we input the x - coordinate And y coordinate into the equation
-2 = -1/4(-2) + c
-2 = 1/2 + c
-5/2 = c
so the full equation is...
y = -1/4x -5/2
