Graph the region that represents the correct solution only once.
Solution
To solve the system of inequalities graphically, we first rewrite the system in a form suitable for graphing. Here are the inequalities provided:
- — This inequality doesn't affect the region since it is trivially satisfied.
- , which simplifies to .
- — This inequality restricts the solution to the region where is non-negative (right side of the y-axis).
- — This restricts the solution to the region where is non-negative (above the x-axis).
Steps to Graph the System of Inequalities:
-
Inequality 1:
- This is a horizontal line at . The region below or on this line (where is less than or equal to 2) is part of the solution.
-
Inequality 2:
- This restricts the solution to the region where , which is the right half-plane (to the right of the y-axis).
-
Inequality 3:
- This restricts the solution to the region where , which is the upper half-plane (above the x-axis).
Graphical Interpretation:
The solution region will be a triangular area bounded by the following:
- The horizontal line ,
- The y-axis ,
- The x-axis .
Corner Points:
The corner points of the solution region are:
- — where the x-axis and y-axis meet.
- — where the line intersects the x-axis.
- — where the line intersects the y-axis.
Bounded or Unbounded:
The region is bounded because it is enclosed on all sides by the x-axis, the y-axis, and the line .
Graphing Summary:
- The region of interest is a triangle with vertices at , , and .
- This region is bounded.

Do you want any more details or have questions?
Here are 5 related questions to expand on the topic:
- How do we identify if a region is bounded or unbounded?
- How do corner points help in solving systems of inequalities graphically?
- What would change if the inequality were instead of ?
- Can the graphical method be applied to non-linear inequalities?
- How do we find the feasible region in a system with more than two variables?
Tip: Always label the axes and the inequality lines when graphing, as it helps in visualizing the solution region easily.
