    Answer:

    The coordinates of point S are (14,-14)

    Step-by-step explanation:

    The midpoint of two points, S(x1, y1) and T(x2, y2) is the point M found by the following formula:

    M={(x1+x2)/2,(y1+y2)/2}

    (7,-5)={(x1+0)/2,(y1+4)/2}

    Solving for x1

    7*2=x1 +0

    14=x1

    Solving for y1

    -5*2=y1 +4

    -10-4=y1

    -14=y1

    Therefore S (14,-14)
