Question 287609: I have some questions about figuring out what types of equations represent what types of graphs. I know that you should rearrange the co-terms. For this equation:(x + 4)^2 - (y - 8 )^2 = 39 is this a graph of a hyperbola? I am not 100% sure, seeing that the standard form of hyperbolas is (x-h)^2/a^2 - (y-k)^2/b^2=1.
Would it be right if I divide each side by 39?
However, I am not sure if the equation is one of a circle....?
Thank you very much for helping.

It is indeed an hyperbola. The best way to find out is graph it
