Answer:
B. (4, 7/2)
Explanation:
To find the midpoint, you must use the formula (change in x)/(change in y). As the x axis changes from -1 to 9, it moves by 10.
As the y axis changes from 2 to 5, it changes by 3.
The middle of -1 and 9 would be 4, as it moves by half of 10, (5) aka
(change in x).
The middle of 2 and 5 would be 3.5, for the same reasoning. (7/2 = 3.5)
Therefore, the answer is B (4, 7/2)
