Answer
$(-3,-3)$ is a solution of the inequality.
Work Step by Step
The given inequality is
$\Rightarrow -6x+4y\leq 6$
Substitute $-3$ for $x$ and $-3$ for $y$.
$\Rightarrow -6(-3)+4(-3)\leq 6$
Simplify.
$\Rightarrow 18-12\leq 6$
$\Rightarrow 6\leq 6$
True.
Hence, $(-3,-3)$ is a solution of the inequality.
