We plot the two points and draw the line:\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "We draw a horizontal green line from the left point until it is\r\n" );
document.write( "exactly above the right point, like this:\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "We count the number of units which is the length of the green line.\r\n" );
document.write( "We count 13.  That number is called the RUN.\r\n" );
document.write( "\r\n" );
document.write( "We draw a red vertical line from the right end of the green line\r\n" );
document.write( "down to the line that we want to find the slope of, like this:\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "We count the number of units which is the length of the red line.\r\n" );
document.write( "We count only 1 unit.  But since it goes DOWN from the green line to the\r\n" );
document.write( "given line, we make it NEGATIVE.  So it is -1. That number -1 is called \r\n" );
document.write( "the RISE.\r\n" );
document.write( "\r\n" );
document.write( "The definition of slope is \r\n" );
document.write( "\r\n" );
