Answer:
(22;-3)
Step-by-step explanation:
if to calculate the coordinates of the given midpoint it needed to use:
![x_{midpoint}=\frac{x_{endpoint1}+x_{endpoint2}}{2};](https://tex.z-dn.net/?f=x_%7Bmidpoint%7D%3D%5Cfrac%7Bx_%7Bendpoint1%7D%2Bx_%7Bendpoint2%7D%7D%7B2%7D%3B)
![y_{midpoint}=\frac{y_{endpoint1}+y_{endpoint2}}{2};](https://tex.z-dn.net/?f=y_%7Bmidpoint%7D%3D%5Cfrac%7By_%7Bendpoint1%7D%2By_%7Bendpoint2%7D%7D%7B2%7D%3B)
then to calculate the coordinates of endpoint2, it needed to perform the substitution:
![\frac{-10+x_{endpoint2}}{2}=6,](https://tex.z-dn.net/?f=%5Cfrac%7B-10%2Bx_%7Bendpoint2%7D%7D%7B2%7D%3D6%2C)
![2=\frac{7+y_{endpoint2}}{2},](https://tex.z-dn.net/?f=2%3D%5Cfrac%7B7%2By_%7Bendpoint2%7D%7D%7B2%7D%2C)
finally:
![x_{endpoint2}=22;](https://tex.z-dn.net/?f=x_%7Bendpoint2%7D%3D22%3B)
![y_{endpoint2}=-3.](https://tex.z-dn.net/?f=y_%7Bendpoint2%7D%3D-3.)
