Which is the equation of a parabola with a directrix at y = 2 and a focus at (5, 0). y = one fourth(x − 5)2 + 1 y = one fourth(x + 1)2 − 5 y = −one fourth(x + 1)2 − 5 y = −one fourth(x − 5)2 + 1

check the picture below.

so, the directrix is above the focus point, meaning the parabola is opening downwards and is vertical, since it's vertical the squared variable is the "x", and since it's opening downwards, the "p" distance from the vertex is negative.   recall that the vertex is half-way between those two folks the focus and directrix, as you see in the picture, and the distance "p" is one, but negative thus p = -1.
