c)![-2x+y-z=1](/tpl/images/0453/4830/4b6b0.png)
Step-by-step explanation:
a)
AB, OB, OA are vectors.
Normalizing AB:![\frac{AB}{||AB||} = (\frac{-4}{\sqrt{24}},\frac{2}{\sqrt{24}}, \frac{-2}{\sqrt{24}})=(-\frac{\sqrt{24}}{6} ,\frac{\sqrt{24}}{12} ,-\frac{\sqrt{24}}{12})](/tpl/images/0453/4830/45c23.png)
b)
OM, OA, OB are vectors.
So,![M = (-1,1,2)](/tpl/images/0453/4830/b64eb.png)
c)
Hence,
