Set 1: Linear Inequalities (Advanced)

Choice A is correct. Choice A is the correct answer. Test the point $(1, 2)$. 1. Check $y > x$: $2> 1$ (True) 2. Check $y < -x + 4$: $2< -1 + 4 \rightarrow 2 < 3$ (True) 3. Result: Both true. Strategic Tip: The solution region is the intersection of the two half-planes. Choice B is incorrect because $2> 2$ is false. Choice C is incorrect because $1> 3$ is false. Choice D is incorrect because $5< 4$ is false.
