Answer:
B. ![B = (4,-2)](https://tex.z-dn.net/?f=B%20%3D%20%284%2C-2%29)
Step-by-step explanation:
GIven that
and
, and that point M is the midpoint of AB, the midpoint can be determined as a vectorial sum of A and B. That is:
![M = \frac{1}{2}\cdot A + \frac{1}{2}\cdot B](https://tex.z-dn.net/?f=M%20%3D%20%5Cfrac%7B1%7D%7B2%7D%5Ccdot%20A%20%2B%20%5Cfrac%7B1%7D%7B2%7D%5Ccdot%20B)
The location of B is now determined after algebraic handling:
![\frac{1}{2}\cdot B = M - \frac{1}{2}\cdot A](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%5Ccdot%20B%20%3D%20M%20-%20%5Cfrac%7B1%7D%7B2%7D%5Ccdot%20A)
![B = 2\cdot M -A](https://tex.z-dn.net/?f=B%20%3D%202%5Ccdot%20M%20-A)
Then:
![B = 2\cdot (1,0)-(-2,2)](https://tex.z-dn.net/?f=B%20%3D%202%5Ccdot%20%281%2C0%29-%28-2%2C2%29)
![B = (2\cdot 1, 2\cdot 0)-(-2,2)](https://tex.z-dn.net/?f=B%20%3D%20%282%5Ccdot%201%2C%202%5Ccdot%200%29-%28-2%2C2%29)
![B = (2,0) -(-2,2)](https://tex.z-dn.net/?f=B%20%3D%20%282%2C0%29%20-%28-2%2C2%29)
![B = (4,-2)](https://tex.z-dn.net/?f=B%20%3D%20%284%2C-2%29)
Which corresponds to option B.
