Solve the following inequalities graphically in two-dimensional plane:
– 3x + 2y ≥ – 6
Given: – 3x + 2y ≥ – 6
Consider: – 3x + 2y = – 6
X | 0 | 2 |
Y | -3 | 0 |
Now draw a solid line – 3x + 2y = – 6 in the graph (∵– 3x + 2y = – 6 is included in the given question)
Now Consider – 3x + 2y ≥ – 6
Select a point (0,0)
⇒ - 3 × (0) + 2 × (0) ≥ – 6
⇒ 0 ≥ – 6 (this is true)
∴ Solution region of the given inequality is above the line – 3x + 2y – 6. (That is origin is included in the region)
The graph is as follows:
