Solve by graphing.
\n" ); document.write( "1. y=x-1
\n" ); document.write( "y=-x+7
\n" ); document.write( "----------
\n" ); document.write( "These are linear eqns, so they're straight lines.
\n" ); document.write( "Find 2 points for each eqn, then draw a line thru them.
\n" ); document.write( "eg, y = x-1
\n" ); document.write( "Pick 2 values for y and find x
\n" ); document.write( "x=0, y=-1 --> (0,-1) point 1
\n" ); document.write( "x=5, y=4 --> (5,4) point 2
\n" ); document.write( "Plot the 2 points, draw a line thru them.
\n" ); document.write( "--------------
\n" ); document.write( "Do the same for the other equation.
\n" ); document.write( "Where they intersect is the solution to the system.
\n" ); document.write( "
