I have to write the equation of a parabola with vertex (0,-6) and Focus (0,5). Since the two x terms are both 0, the parabola will be vertical. I think the equation will be:

(x-0)^2 = 4(?)(y-(-6))

x^2 = 4(?)(y+6)

I can't figure out what "p" should be because I have to multiply it by 4. I know "p" is the distance from the vertex to the focus. I think this might be 11. Is this correct? If not, how do I find it?

Thanks.
