document.write( "First what you need to know is that it is easy.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "It is the easiest thing to learn and to do after learning the multiplication table.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "OK, let' start.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "From the given equation, 2x - 3y = 12, isolate the term with 'y' on the right side  2x - 12 = 3y.\r\n" );
document.write( "\r\n" );
document.write( "    (you move the term 3y from the left side to the right side, changing the sign;\r\n" );
document.write( "     \r\n" );
document.write( "     what you get, 2x - 12 = 3y,  is the same as  3y = 2x - 12).\r\n" );
document.write( "     \r\n" );
document.write( "\r\n" );
document.write( "     Then you divide all the terms by 3, and you get  y = . \r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "In this formula, take x= 0, for simplicity.  You will get  y =  = 0 - 4 = -4.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Next, take x = 3.  You will get  y =  = 2 - 4 = -2.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "You make the table\r\n" );
document.write( "\r\n" );
document.write( "    x   |   y    \r\n" );
document.write( "  ------+------- \r\n" );
document.write( "    0   |  -4\r\n" );
document.write( "    3   |  -2\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, you have two points.  One point is  (x,y) = (0,-4).  The other point is  (x,y) = (3,-2).\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "You can depict/show these point in the graph paper.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Having two points on a paper, you can draw a straight line through these points, using straightedge and a pencil.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "This line is the plot you want to get.\r\n" );
