Hi

foci (-3,-1) and (-3, 9) says it opens Up and Down C(-3, 4)the 4 halfway between 

Foci distance from center = 5   |5 = 

slope  of asymptotes = ± 3/4 says b/a = 3/4  and  5 = 



 Standard Form of an Equation of an Hyperbola opening up and down is:

   with C(h,k) and vertices 'b' units up and down from center,  2b the length of the transverse axis

Foci units units up and down from ) ± b/a
