Observe the graph :
\The ellipse is vertical.
\The center of the ellipse is
.
The vertex of the ellipse are
.
The general form of vertical ellipse is
, where
.
is length of semi major axis and
is length of semi minor axis.
Find the value of
.
is the distance between center and vertex of the ellipse.
The distance between the two points is
.
Substitute
and
.

The value of
.
Find the value of
.
is the distance between center and co-vertex point.
From the graph : One of the co-vertex is
.
The distance between
and
.
and
.
Substitute the values of
,
and
in
.
.
Therefore, the ellipse equation is
.
The ellipse equation is
.
