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 .
