Why the other choices are wrong
Choice A
Choice A is incorrect because it is not equivalent to (does not have the same solution set as) the given inequality. For example, the ordered pair is a solution to the given inequality, but it is not a solution to the inequality in choice A.
Choice C
Choice C is incorrect because it is not equivalent to (does not have the same solution set as) the given inequality. For example, the ordered pair is a solution to the given inequality, but it is not a solution to the inequality in choice C.
Choice D
Choice D is incorrect because it is not equivalent to (does not have the same solution set as) the given inequality. For example, the ordered pair is a solution to the given inequality, but it is not a solution to the inequality in choice D.
