Which point is a solution of x − 2y ≤ −4, x + y ≥ 3, and y ≤ 5?

Answer and explanation

Correct answer: (2, 4)

Answer: (2, 4), so option C is correct. A solution of a system of inequalities must satisfy every inequality at the same time. Test each point directly. For A, (0,2), x - 2y = 0 - 4 = -4, so the first inequality is true, but x + y = 2, and 2 ≥ 3 is false. For B, (4,1), x - 2y = 4 - 2 = 2, and 2 ≤ -4 is false. For C, (2,4), x - 2y = 2 - 8 = -6, so -6 ≤ -4; x + y = 6, so 6 ≥ 3; and y = 4 ≤ 5. All three conditions hold. For D, (-3,6), the value y=6 violates y≤5, even though checking another inequality is unnecessary once one condition fails. Therefore C is the only solution. Memory cue: for simultaneous inequalities, one failed condition rejects the point; every condition must pass.
