The given equation is the same as \"3x%2By=-1\". Being already in standard form makes the work convenient.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The lines you want to find take the forms, \"3x%2By=c\" and \"3x-y=d\", corresponding to the wanted parallel line, and the wanted perpendicular line.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"3%2A4%2B4=c\", and \"3%2A4-4=d\".
\n" ); document.write( "
\n" );
