Answer
No, the columns of this matrix do not form a linearly independent set.
Work Step by Step
Theorem 8 states that if a set contains more vectors than entries in each vector, then the set is not linearly independent. In this case, there are 4 column vectors, but each vector contains only 3 entries.
Equivalently, we can observe that not every column can be a pivot column, since a matrix cannot contain more pivots than rows.
