From the question, we are asked to find thr coordinates of point S.
We know that the midpoint formula M = (x, y) of the two points (x1, y1) and (x2, y2) is:
(x, y) = (x1 + x2/2, y1 + y2/2)
Here the given points are (0, 4) and (2, -8), therefore,
(x, y) = (x1 + x2/2, y1 + y2/2)
------> (x, y) = (0 + 2/2, 4 + (-8)/2)
-------> (x, y) = (0 + 2/2, 4 - 8/2)
-------> (x, y) = (2/2, -4/2)
--------> (x, y) = (1, -2).
