Answer

The graph is shown below.

Work Step by Step

The given inequality is $\Rightarrow y\leq-\frac{3}{2}x+3$. Step 1:- Replace the inequality symbol and graph the linear equation. $\Rightarrow y=-\frac{3}{2}x+3$. The slope is $=\frac{-3}{2}=\frac{rise}{run}$. The $y-$ intercept is $=3$. The line passes through $A=\left(0,3 \right )$. Step 2:- Choose a test point. Let the test point be $B=(0,0)$. Substitute the test point into the inequality. $\Rightarrow (0)\leq-\frac{3}{2}(0)+3$. Simplify. $\Rightarrow 0\leq3$. The statement is correct. Shade the half-plane containing the test point.
