Use the graph to determine whether each system has no solution, one solution, or infinetly many solutions..
\n" ); document.write( "1. Y=x-1
\n" ); document.write( "Y=-x+1
\n" ); document.write( "-----------
\n" ); document.write( "These are straight lines, so you need 2 points.
\n" ); document.write( "y = x-1
\n" ); document.write( "Pick 2 values for x and find y.
\n" ); document.write( "Plot the 2 points.
\n" ); document.write( "Draw a line thru them.
\n" ); document.write( "==============
\n" ); document.write( "The intersection (if any) is the solution.
\n" ); document.write( "Do the others the same way.
\n" ); document.write( "----------------------------------------
\n" ); document.write( "2. X-y=-4
\n" ); document.write( "Y=x+4
\n" ); document.write( "3. Y=x+4
\n" ); document.write( "2x-2y=2
\n" ); document.write( "4. Y=2x-3
\n" ); document.write( "2x-2y=2 \n" ); document.write( "
\n" );
