1. The problem statement, all variables and given/known data If A is a 4x2 matrix, explain why the rows of A must be linearly dependent. 2. Relevant equations 3. The attempt at a solution I put... Since the rank of the matrix is either 0, 1, or 2, I can conclude that the nullility is either 2, 1, or 0. So since there are 4 vectors in a 2 dimensional space, at most two are independent. Therefore the other rows must be dependent. ' Is this anywhere close? Thanks in advance.
