Parabola Directrix

A parabola is the locus of points such that the distance to a point (the focus) equals the distance to a line (the directrix)

Parabola standard equation

4p(y−k)=(x−h)² is the standard equation for an up-down facing parabola with vertex at (h, k),
and a focal length |p|

Rewrite y=9−x² in the standard form: 4(−14 )(y−9)=(x−0)²

(h, k)=(0, 9), p=−14

Parabola is symmetric around the y-axis and so the directrix is a line parallel to the x-axis, a distance −p from the center (0, 9) y-coordinate

y=9−p

y=9−(−14 )

Refine

y=374
