Center: (-1,0)

foci:(-1+/-sqrt1, 0)

vertices: (-1+/-sqrt2, 0)

equations of the asymptotes: y-0=sqrt8/sqrt2(x+1)

Is this correct and if not, how do I figure this out??

yes, center at -1,0 because of(x+1)^2 and (y)^2

a =sqrt 2

b = sqrt 8 = 2 sqrt 2

so vertices at y =0 x = -1+sqrt 2 and -1 -sqrt 2

center to focus = sqrt(2+8) = sqrt 10

so at y = 0 and x = -1 +/- sqrt 10

slope of asymptotes = +/- b/a = sqrt2

so

y = (+/- sqrt 2) - 1

so yes, correct
