Let the other endpoint be ( x1 , y1 )
--------------------------------
The x-coordinate of the midpoint is:
+%28+2+%2B+x%5B1%5D+%29%2F+2+=+5+
+2+%2B+x%5B1%5D+=+10+
+x%5B1%5D+=+8+
---------------------
The y-coordinate of the midpoint is:
+%28+5+%2B+y%5B1%5D+%29+%2F+2+=+1+
+5+%2B+y%5B1%5D+=+2+
+y%5B1%5D+=+-3+
---------------------
The other endpoint is ( 8, -3 )
