You can put this solution on YOUR website!
x+y = 8, so
\n" ); document.write( "y = 8-x\r
\n" ); document.write( "\n" ); document.write( "x+y=-1 so
\n" ); document.write( "y=-1-x
\n" ); document.write( "\"+graph%28+700%2C+700%2C+-5%2C+5%2C+-5%2C+5%2C+8-x%2C+-1-x%29+\"
\n" ); document.write( "The lines are parallel so there are no solutions.
\n" ); document.write( "
\n" );
