    Help with a problem involving distance and midpoint?

    Hello! I posted this question the other day but when my friends and I compared our answers, some of them said their answer is only 4 and not 4 like what I arrived at. The question and my solution to the problem are attached as pictures.

    Shouldn't it be 4 because whether A is (1,-4) or (1,4), its distance to the midpoint of D and Y will still be 4?

    If not, can you please tell me where I went wrong?

    Thank you very much for your help!

    You are correct. $k=\pm 4$.
