Choice A is the correct answer. Match each boundary line to its inequality.

1. $y \leq 2x + 1$: Solid line, shading below.
2. $y \geq -x + 2$: Solid line, shading above.
3. $x \leq 3$: Solid vertical line, shading left.
4. Combine: The intersection of these three regions.

?�� Strategic Tip: Check the direction of shading for each line independently.

Choice B is incorrect because it uses strict inequalities (dashed lines). Choice C is incorrect because it reverses all shading directions. Choice D is incorrect because it swaps $x \leq 3$ for $y \leq 3$ (horizontal vs vertical).
