The focus is at
.
Directrix of the line is
.
Since the directrix of the line is
then the parabola is vertical.
Standard form of the vertical parabola is
, where
is vertex.
If
then the parabola opens to the left and
parabola opens to the right.
Directrix is
and focus at
.

Solve the equations
and
:
Therefore, the vertex of the parabola is
.
Find the value of
.
Substitute
in equation
.
Substitute the values
and
in standard form.

Therefore the parabola equation is
.
Latus rectum is the line segment of a parabola perpendicular to axis which has both ends on the curve.
\The parabola equation is
.
Obtain the points define the latus rectum, consider the
coordinate of focus as
.


The latus rectum points
and
.
Graph :
