Say the slopes are $\"+m%5B1%5D+\"$ and $\"+m%5B2%5D+\"$
\n" ); document.write( "In order to be parallel,
\n" ); document.write( " $\"+m%5B2%5D+=+m%5B1%5D+\"$
\n" ); document.write( "----------------------
\n" ); document.write( "In order to be perpendicular,
\n" ); document.write( " $\"+m%5B2%5D+=+-1%2Fm%5B1%5D+\"$
\n" ); document.write( "---------------------
\n" ); document.write( "The slopes of these equations are
\n" ); document.write( "neither parallel nor perpendicular
\n" ); document.write( "------------------------------
