Hi,
Parabola: Focus F(9, 9), directrix y = -5  V(9,2)  p = 7
 (x-9)^2 = 28(y-2)
the vertex form of a Parabola opening up(a>0) or down(a<0), {{{y=a(x-h)^2 +k}}} 
where(h,k) is the vertex  and  x = h  is the Line of Symmetry
The standard form is {{{(x -h)^2 = 4p(y -k)}}}, where  the focus is (h,k + p)
