Answer: hyperbola;

4(x-5)^2 -25(y+2)^2=100

2)Find the coordinates of the center, the foci, and the vertices, and the equations of the asymptotes of the graph of the equation:

(x+1)^2/2 - y^2/8 = 1

Answer: Center (0,-1);

foci( +/- sqrt10, -10

Vertices ( +/- sqrt2, -1)

Asymptotes: y+1 = +/- Sqrt8/sqrt2(x+1)

Are these problems correct?

Thanks for all your help

In the second, the center is wrong, I didn't go past that.
