Answer:
Option C
Step-by-step explanation:
We know that in a number line numbers all (rational preferably) would be marked on a line in a chronological order.
Mid point of A and B would be the average value of A and B.
Here given that mid point is 2 1/2
This implies average of A and B is 2 1/2
Or total of A and B should be 5
Out of 4 options let us check which gives total 5.
A) (2,3) .. Total is 5
B) (-4,9)..Total is again 5
C) (-4,8)..Total is not 5 but 4
D) (-0.75, 5,75) .. Total is 5
So out of these 4 options only C would not describe a situation where the midpoint between points A and B is 2 1/2
