Algebra practice question
Which of the following points (x, y) satisfies both y > x + 1 and y < −x + 5?
- A. (1, 3)Correct
- B. (3, 3)
- C. (1, 1)
- D. (0, 6)
Answer: A. (1, 3)
For (1, 3): 3 > 2 and 3 < 4, both true.
Why the other answers are wrong
- B. (3, 3)
- (3, 3): 3 > 4 is false.
- C. (1, 1)
- (1, 1): 1 > 2 is false.
- D. (0, 6)
- (0, 6): 6 < 5 is false.
