standard form of hyperbola (horizontal axis)
(x-h)^2 / a^2 - (y-k)^2 / b^2 = 1
asymptote slope m = ± b/a
standard form of hyperbola (vertical axis)
(y-k)^2 / a^2 - (x-h)^2 / b^2 = 1
asymptote slope m = ± a/b
(h,k) => center
a: distance between center and vertices
c^2 = a^2 + b^2
c: distance between center and focus
......................................................................................
vertices (3,-4) and (7,-4) => center: (5, -4), a = 2
foci at (5±√29,-4) => c = √29
b^2 = 25
(x-5)^2 / 4 - (y+4)^2 / 25 = 1
