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
