The hyperbola equation is .

Rewrite the equation as : .

Compare the above equation with .

a = semi - transverse axis = 6,

b = semi - conjugate axis = 2,

Center : (h, k ) = (0, 0),

Vertices : (a, 0 ) and ( a, 0 ) = (6, 0) and ( 6, 0)

         (Substitute : a = 6 and b = 2)

Foci : (c, 0 ) and ( c, 0 ) = .

Asymptotes of hyperbola are :  .

       (Substitute : h = 0, k =0 , a = 6, and b = 2)

Graph of hyperbola:

\
• Draw the coordinate plane.
\
• Plot the center of hyperbola (0, 0).
\
• To graph the hyperbola go 2 units up and down from center point and 6 units left and right from center point.
\
• Use these points to draw a rectangle .
\
• Draw diagonal lines through the center and the corner of the rectangle. These are asymptotes.
\
• The graph approaches the asymptotes but never actually touches them.
\
• Draw the curves, beginning at each vertex separately, that hug the asymptotes the farther away from the vertices the curve gets.
\
• Plot the vertices and foci of hyperbola.
\

The center of the hyperbola is (0, 0), vertices are , foci are ,

asymptotes of the hyperbola are , and the graph is shown below :
