Define \( T : \mathbb{R}^2 \to \mathbb{R}^2 \) by \( T(\mathbf{x}) = A\mathbf{x} \). Find a basis \( B \) for \( \mathbb{R}^2 \) with the property that \([T]_B\) is diagonal.

\[
A = \begin{bmatrix} 2 & -7 \\ -5 & 4 \end{bmatrix}
\]

---

A basis for \( \mathbb{R}^2 \) with the property that \([T]_B\) is diagonal is \(\boxed{\phantom{1}}\).
