WebOct 6, 2021 · Thus, the axis of symmetry is the x -axis. It follows that: 24 = 4p, so p = 6 . Since p > 0, the parabola opens right. the coordinates of the focus are (p, 0) = (6, 0) the equation of the directrix is x = − p = − 6. the endpoints of the latus rectum have the same x -coordinate at the focus.
