a parabola with an axis parallel to theyaxis with vertex (h,k), focus (h,k+p), and directrixy=k−p, withpbeing the distance from the vertex to the focus has eqn:

(x-h)^2 = 4 p (y-k)

Yes, p is the distance from the vertex to the focus, which we can find in this case by taking:

y(focus)-y(vertex) = 5 - - 6 = 11

So yup, you got it all right!
