#### Answer

See the graph

#### Work Step by Step

We are given
$x \gt -3$
$-3x+y \geq 6$
$\rightarrow y \geq 3x +6$
Graph the boundary lines $x \gt -3$ and $y \geq 3x +6$
For $y \geq 3x +6$, use a solid boundary line and shade above it.
The bold pink region of overlap contains the system’s solutions.
