The standard form of an ellipse is
....(2)
Where (h,k) is center of the ellipse.
If a>b, then the vertices of the ellipse are .
From (1) and (2) we get
Since a>b, therefore the vertices of the ellipse are
The vertices of the given ellipse are (10, –7) and (2, –7). Therefore the correct option is C.
