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)
