Answer:

y = -4x - 16 or y +4x + 16 = 0

Step-by-step explanation:

Gradient (m) = -4

Equation of a line given gradient and one point=

y - y = m(x - x) where (x , y ) are the coordinates of the point.

Substituting...

y -(-4) = -4(x -(-3))

y + 4 = -4(x + 3)

y + 4 = -4x - 12

y = -4x - 12 - 4

y = -4x - 16 or y +4x + 16 = 0
