If that is right, I need to find the value of a and b.

comment Finding the coordinates of point on a parabola with a single point on an intersecting line
So, y = -2(a-2)x + a^2 + 2 and to be perpendicular it would have to be y = x /( 2(a-2) ) + a^2 + 2 + b?

The equation of the tangent line would be y = f(a) + f'(a) * (x-a).
