How do u find the two points that define the latus rectum? With the Focus at (0,-7) and the directrix line y=7.
The latus rectum is the line which passes through the focus and is parallel to the directrix.
The equation of the parabola is:
The latus rectum is placed on the line .
To determine the endpoints of the latus rectum calculate the coordinates of the intersection points between the parabola and the line .
