    Exclamation Parametrics - locus of the midpoint - asap help exam tomorrow

    help asap !! i dont know how to find the locus of the midpoint :/

    18.) PQ is a chord of x^2=4ay where P=(2ap, ap^2) and Q(2aq, aq^2).
    a) find the coordinates of point N that divides PQ in the ratio 2:3
    this was easy, just used ratio formula.

    b) find the locus of the midpoint of PQ if pq=2

    I have no clue how to find midpoint, i tried midpoint formula but it didn't work, please help!!
