If you need additional explanations on this, I have a good Lesson PLan on this method here in algebra.com, or go to my website by clicking on my tutor name \"rapaljer\" anywhere in algebra.com.  Look on my homepage for \"Basic Intermediate and College Algebra: One Step at a Time.\"  Select \"Basic Algebra\" and look for Chapter 5 on Graphing.  \r<BR>\n" );

Then, with your pencil on this point, move DOWN 1 unit and RIGHT 1 unit, and plot the second point.  Connect the dots, and you have the second line.  It should look like this:\r<BR>\n" );
