You can put this solution on YOUR website!
I can tell some general things about $\"xy+=+10\"$
\n" ); document.write( "The graph is confined to the 1st and 3rd quadrants
\n" ); document.write( "(+)(+) solutions exist
\n" ); document.write( "(-)(+) no solutions exist
\n" ); document.write( "(-)(-) solutions exist
\n" ); document.write( "(+)(-) no solutions exist
\n" ); document.write( "Neither $\"x\"$ nor $\"y\"$ can be $\"0\"$
\n" ); document.write( "In both 1st and 3rd quadrants, the curves are
\n" ); document.write( "symmetrical about the line $\"y+=+x\"$ because
\n" ); document.write( "if I replace $\"x\"$ with $\"y\"$ and $\"y\"$ with $\"x\"$ ,
\n" ); document.write( "the equation doesn't know the difference
\n" ); document.write( "I'll graph it along with $\"y=x\"$
