You can put this solution on YOUR website! x^2 - y^2 = 8(x-y) + 1 (x+4)^2 - (y + 4)^2 = 1 + 16 -16
 (x+4)^2 - (y + 4)^2 = 1
 Standard Form of an Equation of an Hyperbola opening right and  left is:
 
  with C(h,k) and vertices 'a' units right and left of center,   2a the length of the transverse axis.  e = c/a. Foci are
  =  c- units right and left of center along y = k & Asymptotes Lines passing thru C(h,k), with slopes  m =  ± b/a
 C(4,4) a = 1, b = 1
 V(3,4) and (5,4)
 foci(4+√2, 4) and (4-√2, 4)
 asymptotes: m =  ± b/a =  ± 1
 y - 4 = (x-4),  y = x
 y - 4 = -(x-4), y = x + 8
