The vertices of the hyperbola is
and
.
Since
-coordinates of the vertices are same the transverse axis of the hyperbola is horizontal.
Standard form of horizontal hyperbola is
.
The center of the hyperbola is mid point of vertices
and
.
Center of the hyperbola is
.
The value of
is the distance from each vertex to center.
Distance between one of the vertices
to the center
is
.

.
Asymptotes of the hyperbola is
.
The asymptotes of the horizontal hyperbola are
.
Slope of the asymptote is
.
Positive slope of the asymptote is
.
Substitute
.


.
Substitute
,
and
in

.
Thus, equation of hyperbola is
.
Equation of hyperbola is
