Solve the following inequalities graphically in two-dimensional plane:
x > – 3
Given: x > – 3
Consider: x = – 3
Now draw a dotted line x = – 3 in the graph (∵x = – 3 is excluded in the given question)
Now Consider x > – 3
Select a point (0,0)
⇒ 0 > – 3
⇒ 0 > – 3 (this is true)
∴ Solution region of the given inequality is right to the line x > – 3. (That is origin is included in the region)
The graph is as follows:
