ECZ 2024 · GCE Paper 1 — Linear Programming
Use the diagram. Write the four inequalities that define the unshaded region R.
- A. y ≥ x; x + 2y ≥ 6; y ≥ 1; x ≤ 6
- B. y ≤ x; x + 2y ≥ 6; y ≥ 1; x ≤ 6
- C. y ≤ x; x + 2y ≤ 6; y ≥ 1; x ≤ 6
- D. y ≤ x; x + 2y ≥ 6; y ≤ 1; x ≥ 6
Verified working — step 1
The rising boundary passes through (0, 0) and (6, 6), so y = x.The full step-by-step working and final answer are included with Premium — checked against ECZ marking standards.
