Answer:
The mid-point is (7.5, 8.5).
Explanation:
We are given two points (9,9) and (6,8) as the endpoints for a line segment and we are to find the midpoint of this segment.
We know that the formula for finding the mid point is:
Mid point =

So substituting the given values of the coordinates of the endpoints in the above formula to get:



Therefore, the mid-point is (7.5, 8.5).
