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?

  • Math help -

    hyperbola
    center at (-2,-4)
    eccentricity = √2
    asymptotes y+4 = ±(x+2)
    vertices at x = ±2.5
    foci at x = ±5√2

  • Math help - PS -

    Oops
    vertices at (-2±5,-4)

  • Math help -

    So do I draw lines through the vertices?
