Vertx, exactly between focus and directrix, (0,0).
\n" ); document.write( "9 is distance from vertex and either directrix or focus.
\n" ); document.write( "\"%28x-0%29%5E2=-4p%28y-0%29\"\r
\n" ); document.write( "\n" ); document.write( "\"x%5E2=-4py\", \"p=9\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"-36y=x%5E2\"
\n" ); document.write( "(adjust to any form you want.)
\n" ); document.write( "
