One focus and a directrix:
Use the definition of parabola and the Distance Formula.

Distance from set of points to the focus is equal to distance from set of points to the directrix.

sqrt%28%28x-2%29%5E2%2B%28y-%28-3%29%29%5E2%29=sqrt%28%28x-6%29%5E2%2B%28y-y%29%5E2%29

When that equation makes sense, then simplify it into whatever form you want.
