Multiple Choice

If (x,y) is a point on the parabola y = 3 $x ^ { 2 }$ , then the tangent line to y = 3 $x ^ { 2 }$ passing through (x,y) has slope 6x. Find the equation of the line tangent to y = 3 $x ^ { 2 }$ through the point (-2, 12) .

A) y = 6x + 12
B) y = 12x + 6
C) y = -12x - 12
D) y = -2x + 12
