You can kind of reason this out...the midpoint represents the average of the two endpoints, right?
\n" ); document.write( "Therefore the other endpoint is just as far in both x and y from the midpoint as is the first endpoint.
\n" ); document.write( "Q(-3, -12) ==> (8, -9) ==> P(19, -6)
\n" ); document.write( "
\n" );
