The likely question should or could be, find the equation for the parabola with that vertex and that focus.

The directrix is the line y=2.

The distance-formula definition for Parabola gives %28x-0%29%5E2%2B%28y-%28-2%29%29%5E2=%28x-x%29%5E2%2B%28y-2%29%5E2
.
.
The algebra steps should come to highlight%28x%5E2=-8y%29 or equivalent.
