The distance from the green point on the parabola to the parabola's focus is 9. What is the distance from the green point to the directrix?

In a parabola, the distance from any point on the parabola to the focus is equal to the distance from that point to the directrix. Since the distance from the green point on the parabola to the focus is given as 9, the distance from the green point to the directrix is also 9. Thus, both distances are equal.
