Question
**Problem Statement:**

Let \( T \) be a linear transformation from \( \mathbb{R}^2 \) to \( \mathbb{R}^3 \) and suppose that

\[ 
T \left( \begin{bmatrix} 2 \\ 3 \end{bmatrix} \right) = \begin{bmatrix} 5 \\ 3 \\ -1 \end{bmatrix}, \quad \text{and} \quad T \left( \begin{bmatrix} 5 \\ -1 \end{bmatrix} \right) = \begin{bmatrix} 1 \\ -1 \\ 2 \end{bmatrix}.
\]

**Task (a):**

Express the vector \( \begin{bmatrix} 2 \\ -14 \end{bmatrix} \) as a linear combination of vectors \( \begin{bmatrix} 2 \\ 3 \end{bmatrix} \) and \( \begin{bmatrix} 5 \\ -1 \end{bmatrix} \). Show your work.

**Task (b):**

Use the properties of linear transformations and your answer to part (a) to find \( T \left( \begin{bmatrix} 2 \\ -14 \end{bmatrix} \right) \).

**Visual Representation:**

There are no graphs or diagrams included in the problem statement. The problem consists of matrices and expressions related to linear transformations, which are presented in matrix form.
