Question

Help me solve this linear algebra problem to review for my test.

Let \( T: \mathbb{R}^2 \to \mathbb{R}^2 \) be a linear transformation that maps \( \mathbf{u} = \begin{bmatrix} 3 \\ 5 \end{bmatrix} \) into \( \begin{bmatrix} 6 \\ 1 \end{bmatrix} \) and maps \( \mathbf{v} = \begin{bmatrix} 4 \\ 4 \end{bmatrix} \) into \( \begin{bmatrix} -1 \\ 4 \end{bmatrix} \).

Use the fact that \( T \) is linear to find the images under \( T \) of \( 4\mathbf{u}, 3\mathbf{v}, \) and \( 4\mathbf{u} + 3\mathbf{v} \).

---

The image of \( 4\mathbf{u} \) is \( \boxed{} \).
