Major axis :
to
.
Minor axis :
to
.
Since the
-coordinates of the major axis are same, the major axis is horizontal.
The standard form of horizontal ellipse is
.
Where
,
,
: length of semi major axis,
: length of semi minor axis,
Center :
,
Foci :
,
Vertices :
,
Co-vertices :
,
Major axis :
,
Minor axis :
.
Length of the major axis is equals to
.


.
Length of the minor axis is equals to
.


.
The center of the ellipse is at the mid point of the major axis.
\So,
.
Substitute the values
,
and
in standard form of horizontal ellipse.

.
The ellipse equation is
.
