Question
I thought that a matrix spanned Rn if there was a pivot in every row. However, when a matrix is linearly dependent and the last row is made up of zeroes, it could still end up potentially spanning Rn. I'm a little bit confused about how that works because there isn't a pivot in every row in that situation. How does it still span when there's a free variable? For context, I'm looking at Practice Problem 2 in Section 1.3 of the Vector Equations notes in the textbook
