With reference to the graph above, which of the following solution sets is represented by ΔOPQ?
y ≥ x, y ≤ 0, y + x ≥ 7
y ≤ x, y ≥ 0, y + x ≤ 7
y ≥ x, y ≥ 0, y + x ≤ 7
y ≤ x, y ≤ 0, y + x ≤ 7
y ≤ x, y ≥ 0, y + x ≥ 7
Explanation
from the graph, the solution sets represented by OPQ is the shaded region where y ≤ x, y ≥ 0, and y + x ≤ 7
