Answer:
y+12 = -1/3(x-2)
Explanation:
y = 3x
The slope is 3
Lines perpendicular have a slope that is the negative reciprocal
-1/3 is the slope of a line that is perpendicular
Point slope form is
y-y1 = m(x-x1) where m is the slope and (x1,y1) is the point on the line
y --12 = -1/3(x-2)
y+12 = -1/3(x-2)
