vertex is at (-2,7)
\n" ); document.write( ":
\n" ); document.write( "length of focus is 1/4(5)=1/20 so focus is at (-2,141/20) or(-2,7.05)
\n" ); document.write( ":
\n" ); document.write( "directrix is at y=139/20 or y=6.95
\n" ); document.write( ":
\n" ); document.write( "length of latux rectum is 4(1/20)=4/20=1/5
\n" ); document.write( "
\n" );
