document.write( "I need to graph this problem:y=x+2
\n" );
document.write( " y=2x+1
\n" );
document.write( "I know that the solution is (1,3). Its just every time that I try to graph the equation, my lines dont cross correctly. So that you are not confused with what I am talking about, I am supposed to be solving linear systems by graphing. Please, if you can email this to me before 4/25/06 since it is 4/24/06 that would be great! Thank you and have a great day!
