Determine the null space of the following matrix: $$begin{bmatrix} 1 & 2 & -3& -1 \ -2& -4 &6 &3 end{bmatrix}$$ For this question, I reduced the row echelon form into $$begin{bmatrix} 1 & 2 & -3& -1 \ 0& 0 &0 &1 end{bmatrix},$$ but then I have no idea how to determine the null space, because there's no relationship between $x_1, x_2, x_3, x_4$ .
