document.write( "It depends on whether you are graphing on a NUMBER LINE or on an\r\n" );
document.write( "XY-GRAPH. I'll show you both ways:\r\n" );
document.write( "\r\n" );
document.write( "1. If you are graphing on a NUMBER LINE then this is the way:\r\n" );

document.write( "Then remember the rule \"Less is Left, and gReateR is Right\".  \r\n" );

document.write( "\r\n" );
document.write( "First draw a vertical line through -7 on the x-axis. However \r\n" );
document.write( "you MUST draw it DOTTED.  I can only draw SOLID lines here, \r\n" );

document.write( "\r\n" );
document.write( "Don't forget to draw your vertical line dotted and not solid\r\n" );
document.write( "as I have it here. What I have drawn above is the graph of \r\n" );
document.write( "x < -7, not x < -7.  When you have < or > you must \r\n" );
