    Just want someone to confirm i've done this correctly!

    There is a diagonal line with points A and C at each end. B is the midpoint of this line.
    A has coordinates (1,7)
    B has coordinates (8,2)
    C has coordinates (p,q)

    Find value of p and q.

    I got the answer to be (15, -3)


    (i used the formula)

    Once you've got the co ordinates of point C, you could put A and C back into the formula and see if your answer is point B...I think thats a good method to double check it.
