What does a graph of 16y^2-9x^2=144 look like? For a parabola, state the vertex, the focus, and the equation of the directrix. For a circle, state the center and radius. For an ellipse, state center, vertices, co-vertices, and foci. For a hyperbola, state the center, vertices, and foci.

\n" ); document.write( "16y^2-9x^2=144
\n" ); document.write( "divide both sides by 144
\n" ); document.write( "y^2/9-x^2/16=1
\n" ); document.write( "This is an equation of a hyperbola with vertical transverse axis
\n" ); document.write( "center: (0,0)
\n" ); document.write( "a^2=9
