document.write( "From the point D(1,6) to the center C(4,1),  you move 3 units horizontally in positive direction of x-axis;\r\n" );

document.write( "\r\n" );
document.write( "    hence, to get the other diameter's endpoint, you CONTINUE to move another 3 units horizontally along x-axis\r\n" );

document.write( "    from coordinate x= 4 (center) to x= 4+3 = 7 (endpoint).\r\n" );

document.write( "    hence, to get the other diameter's endpoint, you CONTINUE to move another 5 units vertically along y-axis\r\n" );

document.write( "Thus, the other midpoint coordinates are  x= 7,  y =-4,  and the endpoint itself is (7,-4).     ANSWER\r\n" );
