Derive the equation of the parabola with a focus at (2, 4) and a directrix of y = 8. I've tried answering this myself using the right formula, but I keep getting nothing even close to the answer choices. Not sure if I'm squaring wrong or whatever. Help???

What do you think it is first?

OpenStudy (bloosweater):

I got y = 1/24 (x - 2)^2 - 2
