The distance from the vertex and focus .

Here coordinate of the vertex and focus is zero and focus is in the form where .

Thus the parabola is vertical and opens down.

Standard form of vertical parabola: .

Substitute in .

Points of latus rectum can be found by substituting  in .

.

Points that define latus rectum are .

Graph the parabola.

Plot the vertex and focus.

Draw the latus rectum and directrix line.

The parabola equation is and points on latus rectum are .
