\r\n" );
document.write( "Notice that the segment from P1 to the given midpoint is a vertical line.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "It is so, because first coordinate x= -3 is the same for both points P1 and the midpoint.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "It means that the second endpoint has the same coordinate x= -3, and half of the problem is just solved in this way.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Thus you only need to determine y-coordinate of the second endpoint, which is easy now, after my hint.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Answer.  P2 = (-3,-6).\r\n" );
