If we have 2 points, P1(x1, y1) and P2(x2, y2), the medium point M will have coordinates equal to the medium values of the coordinates of P1 and P2.
M(xM, yM) = ((x1+x2)/2, (y1+y2)/2)
Therefore, applying to our case, we can see that the medium point will have coordinates
M(xM, yM) = ((x1+x2)/2, (y1+y2)/2) = ((-5-2)/2, (4+5)/2) = (-7/2, 9/2)
