What is the distance between a given point on a parabola and the parabola’s focus if the distance between the same given point and the parabola’s directrix is 5 units?

• 5 units

parabolas are geometrically defined as a set of points that're equidistant from a focus point and a directrix line.

equidistant means equally distant.

distance between the given point on parabola and the directrix is 5 units.
therefore, by definition, dist. between given point and the focus is also 5 units.
