7. Provide a step by step explaination that includes any definitions or theorems. Try to be as detailed as possible in your explaination.

**Problem 7:**

Let \( T: \mathbb{R}^2 \to \mathbb{R}^2 \) be the reflection about the line \( 3x = 2y \).

(a) Find a basis \(\beta = \{v_1, v_2\}\) for \(\mathbb{R}^2\) so that \( [T]_{\beta} = \begin{pmatrix} 1 & 0 \\ 0 & -1 \end{pmatrix} \).

(b) Use your answer to the previous part and the corollary on page 115 to find the standard matrix of the linear transformation \( T \).
