solve by graphing:
\n" ); document.write( "x-y=2
\n" ); document.write( "x+y=-4
\n" ); document.write( "----------
\n" ); document.write( "Each eqn is a straight. 2 points is sufficient to plot a straight line.
\n" ); document.write( "x-y=2
\n" ); document.write( "x = y+2
\n" ); document.write( "Pick values for y and find x
\n" ); document.write( "y...x
\n" ); document.write( "0...2 --> (2,0)
\n" ); document.write( "4...6 --> (6,4)
\n" ); document.write( "Plot the 2 points and draw a line thru them.
\n" ); document.write( "-------------
\n" ); document.write( "x+y=-4
\n" ); document.write( "y = -x-4
\n" ); document.write( "x...y
\n" ); document.write( "0...-4 --> (0,-4)
\n" ); document.write( "4...0 ---> (4,0)
\n" ); document.write( "Draw a line thru the points.
\n" ); document.write( "Where they intersect is the solution.
\n" ); document.write( "
\n" );
