    The midpoint of  (x_1,y_1) and  (x_2,y_2)
    is  (\frac{x_1+x_2}{2},\frac{y_1+y_2  }{2})

    You just need to work out the average of the x and y coordinates.

    Midpoint of 2 points, for midpoint x coordinate add together the two x coordinates of original Pts and divide by 2. For y coordinate of midpoint Add together two y coordinates of original Pts and divide by 2.
    Should give (1, 7.5) for your Q1.
    For q2 think about how you find the midpoint and work in reverse to find the other original Pt.
