Practice Question
Each of the following is a solution to the equation x- 2y = 4 EXCEPT
Answer Choices
- A: (-2,-3)
- B: (0,2)
- C: (4,0)
- D: (8,2)
Correct Answer: B
Rationale: Test each: (−2, −3): x−2y = −2 + 6 = 4 ✓; (0, 2): x−2y = 0 − 4 = −4 ✗; (4, 0): x−2y = 4 ✓; (8, 2): x−2y = 8 − 4 = 4 ✓. So, the incorrect one is (0, 2). Only (0, 2) gives −4 instead of 4 when substituted into the equation x − 2y = 4.
