The vertex is
, the axis of symmetry is
-axis and containing the point
.
The axis of symmetry is
-axis then the parabola is horizontal and it passes the point 
since the parabola is opens right side.
\The general form of parabola is
.
Substitute

.
The focus of the parabola is
.
\
Substitute
and
.
The focus 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 is
.
Substitute
and

The points are
and
determine the latus rectum.
The line
is the directrix.
