Final answer:
The question lacks the necessary inequality to determine which test points make it true; however, if the condition is simply x = -15, then test point C: x = -15 would be correct.
Step-by-step explanation:
The question seems incomplete as the inequality to test the points against is not provided. However, the student is asking us to select the test points that would make an unspecified inequality true when X = -15. Without knowing the inequality, we cannot decisively determine which of the given test points (A: x = 0, B: x = 30, C: x = -15, D: x = 12) would satisfy the condition. If the inequality to be tested were simply x = -15, then the test point that would make this inequality true is obviously C: x = -15. However, in the absence of the actual inequality, we cannot provide a definitive answer to the student's question.
