Geometry ?

I'm struggling finding the solution with a Geometry problem.  Midpoint (0,-3) and A(2,1) what is B coordinate points ? The answer I get is -2,-7. My system says I'm wrong.  Can someone please help me out with this?  Thank you

    A(2, 1) and Midpoint (0, -3) 

    B coordinate points (-2, -7)

    Your answer (-2, -7) is  correct.

    Yes, M = (A+B)/2, so B = 2M - A = 2(0,-3) - (2,1) = (-2,-7).

    You're right, unless you entered it wrong; maybe you need the parentheses (-2, -7)?
