document.write( "Equations of parallel lines need differ only by their constant term(s).\r\n" );
document.write( "\r\n" );
document.write( "y = 2x-7 has only the constant term -7.  Substitute any letter for the constant\r\n" );
document.write( "term, say b.\r\n" );
document.write( "\r\n" );
document.write( "y = 2x+b\r\n" );
document.write( "\r\n" );
document.write( "Now all we need do is substitute the point (5,-1) in it\r\n" );
document.write( "\r\n" );
document.write( " -1 = 2(5)+b\r\n" );
document.write( " -1 = 10+b\r\n" );
document.write( "-11 = b\r\n" );
document.write( "\r\n" );
document.write( "Substitute 11 for b in\r\n" );
document.write( "\r\n" );
document.write( "y = 2x+b and get\r\n" );
document.write( "\r\n" );
