Question

linear algebra: span?

Do the following vectors [1 3], [2 -3]. [0 2] and [2 3], [-1 2] span R2(1x2 matrices)?
I think the answer is yes for both.. am I right?

Answer 1

Sorry, I made a spelling error. The last two vectors are [2 4], [-1 2]

Answer 2

to span R2 you need 2 not paralel vectors, and you got that

Answer 3

So both "sets" of vectors span R2?

Answer 4

yes, in bouth sets there are at least 2 independent vectors, so they span R2

Answer 5

alright thanks!
