\r\n" );
document.write( "\r\n" );
document.write( "Plot the two points:\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Draw a straight line through them:\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The line goes uphill to the right, so its slope\r\n" );
document.write( "will be a positive number.\r\n" );
document.write( "\r\n" );
document.write( "Draw a green line from (6,8) till it is exactly below (8,9).\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "That green line is called a \"run\". Notice that it is 2 units\r\n" );
document.write( "long,  So the run is 2\r\n" );

document.write( "Next draw a red line from the end of the green line up to the\r\n" );
document.write( "point (8,9).\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "That red line is called a \"rise\". Notice that it is 1 unit\r\n" );
document.write( "long,  So the rise is 1.\r\n" );

document.write( "Now the slope is defined as \"%28rise%29%2F%28run%29+=+1%2F2\"\r\n" );

document.write( "So the slope is 1/2, positive because it goes uphill to\r\n" );
