Step-by-step explanation:
Answer:
b-2=n
No, it isn't.
We have and let be the subset of of all points on the line
We need to find if is a subspace of the vector space .
In all the possibilities for own subspace of the vector space are :
We know that is the subset of of all points on the line
If we look at the equation, the point doesn't verify it because :
Which is an absurd. Therefore, doesn't contain the origin (and is a line in ). Finally, it can't be a vector space of
