Solve each system by graphing.
\n" ); document.write( "x + y = 4
\n" ); document.write( "2x - y = 5
\n" ); document.write( "-------------
\n" ); document.write( "Plot 2 points for each eqn on graph paper, then draw a line thru the 2 points.
\n" ); document.write( "x +y = 4
\n" ); document.write( "-------
\n" ); document.write( "0 4
\n" ); document.write( "4 0
\n" ); document.write( "----
\n" ); document.write( "2x - y = 5
\n" ); document.write( "x y
\n" ); document.write( "----
\n" ); document.write( "0 -5
\n" ); document.write( "5 +5
\n" ); document.write( "------
\n" ); document.write( "Where the lines cross is the solution.
\n" ); document.write( "
\n" );
