You can put this solution on YOUR website! 
 or
this is an ellipse with  and  ; so, the center is at
( , )
we also know that semi-major axis  and semi-minor axis  ; so, we have an ellipse with horizontal major axis
vertices:
( , ) =>( ,)=>( ,)
( ,)=>( ,)=>( ,)
c0-vertices:
(, ) =>(, )=>(, )
(, )=>(, )=>(, )
foci:
The formula generally associated with the focus of an ellipse is
so, and
 and
