A parabola can be drawn given a focus of (-9, -7) and a directrix of x = 9. Write the equation of the parabola in any form.

Check the picture below, so the parabola looks more or less like so, with a vertex at (0 , -7), let's recall the vertex is half-way between the focus point and the directrix.

so this horizontal parabola opens up to the left-hand-side, meaning that the "P" distance is a negative value.

multiple all that
