Answer:
Given x+y≥4
Let us draw the graph of x+y=4
Put x=0⟹0+y=4⟹y=4
(0,4) is the solution set of x+y=4
Put y=0⟹x+0=4⟹x=4
(4,0) is the solution set of x+y=4
⟹(4,0),(0,4) lies on the line x+y=4
(0,0) lies in the left side area of x+y=4
Let us check that (0,0) lies in the area of solution set of x+y≥4
x+y=0+0<4
⟹(0,0) does not lies in the area of solution set of x+y≥4
∴ solution set is the area which right side of x+y=4
