x + y ≥ 4 … (1)
2x – y < 0 … (2)
The graph of the lines, x + y = 4 and 2x – y = 0 are drawn in the figure below.
Inequality (1) represents the region above the line x + y = 4. (including the line x + y = 4)
It is observed that (–1, 0) satisfies the inequality, 2x – y < 0.
[2(-1) – 0 = -2< 0]
Therefore, inequality (2) represents the half plane corresponding to the line, 2x – y = 0 containing the point (-1, 0). [excluding the line 2x – y < 0]
Hence, the solution of the given system of linear inequalities is represented by the common shaded region including the points on the line x + y = 4 and excluding the points on line 2x – y = 0 as follows:
