To find: the inequality whose solution is the shaded region
Answer to Problem 19E
Therefore, the inequality whose solution is the shaded region is
Explanation of Solution
Given:
Calculation:
From the graph, observe that the line is a dashed line that means the inequality is either
< or >
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 lies in the shaded region,
Therefore, the inequality whose solution is the shaded region is
Conclusion:
Therefore, the inequality whose solution is the shaded region is
