<u><em>The correct answer is:</em></u>(-1, -14).
<u><em>Explanation:</em></u>The way to find a midpoint is by taking <u>the average of each coordinate.</u>
Since the x values are -10 and 8, the average would be -1:
</span>
![\frac{-10+8}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B-10%2B8%7D%7B2%7D%20)
<span> = -1.
Since the y values are -11 and -17, the average would be -14:
</span>
![\frac{-11+-17}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B-11%2B-17%7D%7B2%7D%20)
<span> = -14.
<u>Therefore the ordered pair is (-1, -14)</u></span>
