Are m1=7/4, m2=4/7 parallel, perpendicular or neither?
\n" ); document.write( "=====================
\n" ); document.write( "Parallel --- slopes are equal
\n" ); document.write( "Does m1 = m2?
\n" ); document.write( "-----
\n" ); document.write( "Perpendicular --- slopes are negative inverses, ie, the product of the 2 slopes = -1
\n" ); document.write( "Is m1*m2 = -1?
\n" ); document.write( "
\n" );
