Answer
Center: $(2,-1)$
Vertices: $(-2,-1) , (6,-1)$
Foci: $(-3,-1) , (7,-1)$
Work Step by Step
The horizontal transverse axis is: $a=4; b=3$
The center of the hyperbola is: $(2,-1)$
Vertices: $(h \pm a , k)=(-2,-1) , (6,-1)$
Now, $c=\sqrt {a^2+b^2}=\sqrt {4^2+3^2}=5$
Foci: $(h \pm c , k)=(2 +5 , -1), (2 -5 , -1)=(-3,-1) , (7,-1)$
