Final answer:
The coordinates of the midpoint can be found using the midpoint formula: A) (u + s) / 2, (v + 9) / 2.
Step-by-step explanation:
The coordinates of the midpoint of the segment connecting points (u, v) and (s, 9) can be found using the midpoint formula:
x-coordinate of midpoint: (u + s) / 2
y-coordinate of midpoint: (v + 9) / 2
So the formula that gives the coordinates of the midpoint is:
( (u + s) / 2 , (v + 9) / 2 )
