This and your other two exercises are based purely on the definition of a parabola. See these two lessons:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "equation of parabola using distance formula, given directrix and focus\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Same idea, but vertex not at origin, and different orientation
\n" ); document.write( "
\n" );
