Hi,
Standard Form of an Equation of an Hyperbola is
where Pt(h,k) is a center with vertices 'a' units right and left of center.
Asymptotes passing thru the center with slope = ± b/a
foci being ± sqrt(a^2 + b^2)from center along axis of symmetry y = k

asymptote slope b/a = 3/4
foci (-2,-8) and (8,-8). c = sqrt(16+9) = 5, C(3,-8)
