Choice A is the correct answer. Match line type and shading.

1. Solid line: Inclusive ($\leq$ or $\geq$).
2. Below: Less than ($\leq$ or $<$).
3. Combine: $\leq$

?�� Strategic Tip: "Below" always corresponds to $<$ or $\leq$.

Choice B is incorrect because it implies a dashed line. Choice C is incorrect because it shades above. Choice D is incorrect because it shades above and implies a dashed line.
