Answer:
Step-by-step explanation:
try the numbers -3 -2 1 and 3
A midsegment is given by the formula:
![\frac{x1+x2}{2} , \frac{y1+y2}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx1%2Bx2%7D%7B2%7D%20%2C%20%5Cfrac%7By1%2By2%7D%7B2%7D)
Where x1, x2, y1, and y2 correspond to their respective coordinates. We can do the equation:
![\frac{-3+5}{2} , \frac{-1+3}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B-3%2B5%7D%7B2%7D%20%2C%20%5Cfrac%7B-1%2B3%7D%7B2%7D)
This gets us a midpoint coordinate of <span>
(1,1)</span>As for distance, it will be found by doing:
![\sqrt{(x2-x1)^2+(y2-y1)^2}](https://tex.z-dn.net/?f=%20%5Csqrt%7B%28x2-x1%29%5E2%2B%28y2-y1%29%5E2%7D%20)
We can do the following:
![\sqrt{(5-(-3))^2+(3-(-1))^2}](https://tex.z-dn.net/?f=%20%5Csqrt%7B%285-%28-3%29%29%5E2%2B%283-%28-1%29%29%5E2%7D%20)
![\sqrt{(8)^2+(4)^2}](https://tex.z-dn.net/?f=%20%5Csqrt%7B%288%29%5E2%2B%284%29%5E2%7D%20)
![\sqrt{64+16}](https://tex.z-dn.net/?f=%20%5Csqrt%7B64%2B16%7D%20)
This simplifies to
![4 \sqrt{5}](https://tex.z-dn.net/?f=4%20%5Csqrt%7B5%7D%20)
