\textbf{131-} The reflection of line $\Delta$ across the line $y = -x$ is line $\Delta'$. The equation of line $\Delta$ is $2y + x = 6$. With respect to line $x = -x$, the equation of line $\Delta'$ is which of the following?
\medskip
(1) $y + 2x = -6$ \hfill (2) $y + 2x = 2$ \hfill (3) $y + 2x = -2$ \hfill (4) $y - 2x = \Lambda$
