Sketch the graph: (x+2)^2/25-(y+4)^2/25=1

I don't understand this at all! When I tried graphing it I just had two lines going through the center, which is (-2,-4). But it should be a hyperbola, right? Could anyone help me?

hyperbola
center at (-2,-4)
eccentricity = √2
asymptotes y+4 = ą(x+2)
vertices at x = ą2.5
foci at x = ą5√2

Oops
vertices at (-2ą5,-4)

So do I draw lines through the vertices?
