Drawing linear graphs — practice question

Region $R$ is determined by the inequalities $y \leq 2x$, $3x + 4y \geq 12$, and $x \leq 3$. The coordinate grid shown has $x$ ranging from $0$ to $5$ and $y$ ranging from $0$ to $7$.

On the grid, construct and label the region $R$ that meets these inequalities. Shade the regions that are not needed.
