The directions say \"Solve the systems of equations by graphing. Then classify the system.\" The problem has 4 graphs to choose from(they won't let me copy so I can't paste,lol). I think if you could give me the coordinates I could figure out which graph they go to. Than-x in advance,you've saved a lot of grey hairs:-) The equations are:     <BR>\n" );
