I'm not sure if this is the most efficient way, but you have to start by finding the perpendicular line to y = 3x + 2 that has (5, 3)

y = -1/3x + 14/3

y = -1/3x + 14/3 and y = 3x + 2 intersect at (.8, 4.4)

If (.8, 4.4) is the center point, and (5, 3) is the other point, then the final point is (-3.4, 5.8)

I'm sorry if that was confusing.
