slope of:
\n" ); document.write( "y=3x-6
\n" ); document.write( "is 3
\n" ); document.write( ".
\n" ); document.write( "a line perpendicular must have a \"negative reciprocal\".
\n" ); document.write( "So, if we
\n" ); document.write( "Let m = slope of perpendicular line
\n" ); document.write( "then
\n" ); document.write( "3m = -1
\n" ); document.write( "m = -1/3 (this is your slope)
\n" ); document.write( "
\n" ); document.write( "
\n" );
