Given the focus and the directrix of a parabola, we can find the parabola's equation. Consider, for example, the parabola whose focus is at ( − 2, 5) and directrix is y = 3 . We start by assuming a general point on the parabola ( x, y) . Using the distance formula, we find that the distance between ( x, y) and the focus ( − 2, 5) is ( x + 2 ...
