If two lines are perpendicular, their slopes must be \"negative reciprocal\".
\n" ); document.write( "That is:
\n" ); document.write( "Let x = slope of L2
\n" ); document.write( ".
\n" ); document.write( "Then, for L1 and L2 to be perpendicular, it must be:
\n" ); document.write( "3x = -1
\n" ); document.write( "x = -1/3
\n" ); document.write( ".
\n" ); document.write( "Therefore, the slope of L2 is -1/3
\n" ); document.write( "
\n" );
