I would really appreciate your help, if anyone can give it. I'm so stuck.

I've got a worksheet due and I've got two problems that I'm stumped on.

1) Find the foci of a hyperbola with the equation 9y^2-72y-16x^2-64x-64=0

2) Find the slopes of the asymptotes of a hyperbola with the equation y^2=36+4x^2.

If you would, please explain your steps so I can understand what you're saying.

Much appreciated
