The Solution set of the inequality three 3x+4y≤123x + 4y \leq 12 is :

Solution

✅ Correct Option: 4

Test origin (0, 0) in 3x+4y≤123x + 4y \leq 12: 0≤120 \leq 12 is TRUE.

Since the inequality is ≤\leq (not strict), the boundary line is included.

Thus the solution is the half plane containing the origin INCLUDING the line.
