No. Not like that!

One end point given is C(-4,-5), and the midpoint is M(3,-6), so choose or use the UNKNOWN other endpoint as some U(x,y).

The coordinate values according to the midpoint formula would be arranged like this:
%28x%2B%28-4%29%29%2F2=3, and %28y%2B%28-5%29%29%2F2=-6
Just solve for x and for y. You will then have the unknown endpoint U(x,y).
