 *****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 
  opens left/right C(3,-8) , a = 5, 2a = 10, the length of transverse axis
 the slopes of the asymptotes =  ±b/a = ±3/5
 See below descriptions of various conics
 Standard Form of an Equation of a Circle is
   where Pt(h,k) is the center and r is the radius
 Standard Form of an Equation of an Ellipse is
   where Pt(h,k) is the center. (a variable positioned to correspond with major axis)
 a and b  are the respective vertices distances from center
 and ±
  are the foci distances from center: a > b 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 center, along x = h & Asymptotes Lines passing thru C(h,k), with slopes m =  ± b/a

  units right and left of center along y = k & Asymptotes Lines passing thru C(h,k), with slopes  m =  ± b/a
 
 the vertex form of a Parabola opening up(a>0) or down(a<0),
   where(h,k) is the vertex  and  x = h  is the Line of Symmetry
 The standard form is
  , where  the focus is (h,k + p) the vertex form of a Parabola opening right(a>0) or left(a<0),
  where(h,k) is the vertex and  y = k  is the Line of Symmetry
 The standard form is
  , where  the focus is (h +p,k )
