Hey guys.

I can calculate the basis of a matrix, but I'm a little unsure as to what they are asking here, if you could provide a bit of insight that would be awesome

Given that A represents all the the vectors in R3, and A = {(a,b,c): c = a – b and a, b, c R}.

Now if I don't have actual values, other than what's given above. What should I say for the basis for A and what is the dimension of A?

Thanks
