Graphing: help finding the vertices, center and foci of the ellipse.

Can i possibly get some help to find the vertices, the foci and the center of the following graph:
(x+1)^2 /16 - (y-3)^2 /9 = 1...............?

This is not an ellipse:)

Because of the minus sign, it is an hyperbola.

Horizontal Hyperbola, since x is first
center (-1, 3)
a= sqr(16)=4
b= sqr(9)=3
Vertices ( -5,3) and (3,3) ...4 units right and left from the center.

c^2=a^2+b^2=25, c=5

Foci are 5 units from center, foci( -6,3) and (4,3)

Hoping this helps!
