Answer:
(11,-2)
Explanation:
Given:

- P is located at (8,10)
- S is located at (12,-6)
To find:
Solution:
We need to find coordinates of R first and we can find the coordinates of Q using the midpoint formula.
The midpoint formula states that the coordinates of the midpoint of a segment with endpoints (x1, y1) and (x2, y2) are:

In this case, the endpoints of the segment are P(8,10) and S(12,-6), so the coordinates of R are:

Since, the coordinate of R is (10, 2) and Q is the midpoint of R and S.
So, we can need to use midpoint formula again;
In this case, the endpoints of the segment are R(10,2) and S(12,-6), so the coordinates of Q are:

Since, the coordinate of Q is (11, -2).
So, the answer is (11,-2)
