figuring out orthonormal basis for a matrix?

For $T in mathcal{L}(mathbb{R}^2)$ given by $T(x,y) = (x, -y)$, its basis is $ mathcal{M}(T) = begin{pmatrix}1 & 0\0 & -1end{pmatrix}$. How would I find the orthonormal basis for this? Is $frac{1}{sqrt{2}}(x + y), frac{1}{sqrt{2}}(x - y)$ one? How would I figure this out?

It is the usual basis ${(1,0), (0,1)}$.

It is the usual basis ${(1,0), (0,1)}$.
