You can put this solution on YOUR website!
Let the coordinates of the other endpoint
equal ( x,y )
+%28+-2+%2B+x+%29+%2F+2+=+-4+
+-2+%2B+x+=+-8+
+x+=+-6+
----------------
+%28+4+%2B+y+%29+%2F+2+=+-6+
+4+%2B+y+=+-12+
+y+=+-16+
-------------
The coordinates of the other endpoint
are (-6, -16 )
----------------
I don't get one of the choices
