The answer above is NOT correct.
Find a basis for the subspace of $\mathbb{R}^4$ consisting of all vectors of the form
$\begin{bmatrix} x_1\\6x_1+x_2\\-2x_1-9x_2\\3x_1+5x_2 \end{bmatrix}$
Answer: [1,-1,0,0], [0,1,0,0]

To enter a basis into WeBWork, place the entries of each vector inside of brackets, and enter a list of these vectors, separated by commas. For instance, if your basis is $\begin{Bmatrix}\begin{bmatrix} 1\\2\\3 \end{bmatrix}, \begin{bmatrix} 1\\1\\1 \end{bmatrix}\end{Bmatrix}$, then you would enter [1,2,3], [1,1,1] into the
answer blank.
Result
incorrect
