ECZ 2017 · O-Level Paper 1 — Linear Programming
The diagram shows an unshaded region R bounded by straight lines. Write down the four inequalities that define region R.
- A. x > 1, x ≤ 5, y ≤ 6, y ≥ x − 2
- B. x > −1, x ≤ 4, y ≤ 6, y < x − 2
- C. x > −1, x ≤ 4, y ≤ 6, y > x − 2
- D. x < −1, x ≥ 4, y ≥ 6, y < x − 2
