<u>Answer:</u>
The mid-point is (7.5, 8.5).
<u>Step-by-step explanation:</u>
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:
<em>Mid point =
</em>
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).

Answer:

Step-by-step explanation:
To find slope using two points you need to find the difference in x and y. You use 
So, 2-0=2 and 5-(-4)=9. Therefore the slope is 2/9x
