Answer: y = -4x + 6
Explanation:
supposing m1 is the gradient of the line for whose equation we want to find
m1 * m2 =-1 for perpendicular lines
if m1 = 1/4
meaning m2 = -4
m2= -4 at point (2,-2)
we can get value of constant c
y = mx =c
-2 = (-4)(2) +c
c = 6
substituting c and m2 in gen eqn of line : y =mx +c
y = -4x + 6
