    Answer:

    The coordinates of point X are (-11/2, 5/2)

    Step-by-step explanation:

    To find the coordinates of X , we shall apply the midpoint formula;

    Mathematically, that would be;

    (x , y) = (x1 + x2)/2 , (y1 + y2)/2

    From the question

    x1 = -3 , x2 = -8

    y1 = 1 , y2 = 4

    So substituting these values, we have;

    (x ,y) = (-3-8)/2, (1 + 4)/2

    (x ,y) = -11/2, 5/2
