Question

Represent to solution set of the inequations graphically in two dimensional plane:

x + 2y ≥ 6

Answer 1

Firstly, we shall plot the graph of the equation and shade the side containing solutions of the inequality,

Now, we can choose any value but find the two mandatory values which are at x = 0 and y = 0, i.e., x and y–intercepts always,

x + 2y ≥ 6

Therefore when,

x	0	2	6
y	3	2	0
