To find: the inequality whose solution is the shaded region

Answer to Problem 17E
Therefore, the inequality whose solution is the shaded region is
Explanation of Solution
Given:
Calculation:
From the graph, observe that the line is a solid line that means the inequality is either
Take a point (2,-1) that lies in the shaded region.
Assume
Substitute 2 for
Since, the statement
Assume
Substitute 2 for
This means that for any point that lie in the shaded region, the
Therefore, the inequality whose solution is the shaded region is
Conclusion:
Therefore, the inequality whose solution is the shaded region is
