Which equation represents a parabola with a focus of (-2,5) and a directrix of y=9 regent?

When the distance from the vertex to the focus is "p" and the vertex is (h, k), the equation of the parabola can be written as
  y = (1/(4p))(x -h)² +k

Of course, p is half the distance between the focus and the directrix, so is
  (1/2)(5 - 9) = -4/2 = -2
The vertex is (-2, 7), so the equation of the parabola can be written as
  y = (-1/8)(x +2)² +7
