Pl0t these points on the graph, join them , you get a straight line which is represented by 2x + 4y = 8.
Choose some point, say (5,5) When you substitute this in the given equation you get
10 + 20 < 8
30 < 8 which is not true, which means the point (5,5) is not in the required region. so shade the region which is on the other side of the line.
