Let's say you're asked if v3 is a linear combo of the other two vectors.

Rref of the matrix gives

1 0 1

0 1 0

0 0 0

The definition of a Linear combo is v3=c1v1+c2v2 where c1 and c2 are scalars.

Okay do this is where I get con fused . If u look at the above matrix c2=0 which means v3=c1v1. Would that mean its not a linear combination of v2 since c2=0?

Also is 0 a scalar?
