Foci : .
Length of the major axis is .
Since the -coordinates of the foci are same, the ellipse 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 .
.
The center of the ellipse is the mid point of the foci.
\So, .
The distance between the foci is equals to .
.
Consider .
.
Substitute the values ,
and
in standard form of horizontal ellipse.
.
The ellipse equation is .
