**Problem Statement:**

Determine whether the set of vectors in \( M_{2,2} \) is linearly independent or linearly dependent.

**Given Matrices:**

\[
A = \begin{bmatrix} 2 & -1 \\ 4 & 5 \end{bmatrix}, \quad 
B = \begin{bmatrix} 5 & 3 \\ -3 & 3 \end{bmatrix}, \quad 
C = \begin{bmatrix} 2 & -8 \\ 22 & 23 \end{bmatrix}
\]

**Options:**

- ⬤ Linearly independent
- ⬤ Linearly dependent

**Explanation:**

In this problem, you are asked to determine the linear dependence or independence of a set of given matrices. Each matrix is a \(2 \times 2\) matrix, represented by \(A\), \(B\), and \(C\).

- **Matrix A** is defined as having elements \([2, -1]\) in the first row, and \([4, 5]\) in the second row.
- **Matrix B** contains elements \([5, 3]\) and \([-3, 3]\).
- **Matrix C** includes \([2, -8]\) and \([22, 23]\).

To determine if the set is linearly independent or dependent, you generally check if any matrix can be written as a linear combination of the others. If this is possible, the matrices are linearly dependent; if not, they are linearly independent.
