Answer:

y=3/2x-44

Explanation:

The gradient to the line y=-⅔x+8 is -⅔

The product of the gradients of a line and its perpendicular line is equal to -1.

Hence:-⅔×__=-1

Gradient to the perpendicular line is 3/2

You then proceed to find the equation of the perpendicular line:

difference in y axis/difference in x axis=gradient

(y-(-16)/x-4)=3/2

2y+32=3x-12

2y=3x-44

y=3/2x-44
