Answer:
(-3,0)
Step-by-step explanation:
The two points that are located on the line y=5 are (-3,5) and (8,5), so the other two points have to be on the same line y=0 because of the y coordinate in (8,0). The shape is a rectangle so the the distance between (-3,5) and (8,5) will be the same as (8,0) and S. So, S has to be at (-3,0).
