The distance from x1 to the midpoint is the same as the distance from the midpoint to x2. The distance is 3.5 to the midpoint, and 2.5+3.5=6. That is the x-coordinate.
\n" ); document.write( "The y distance is 5.5 to the midpoint, and 4.5+5.5 is 10\r
\n" ); document.write( "\n" ); document.write( "the values are (6, 10) for the other endpoint.
