Math Problem Statement
Graph the solution of the system of linear inequalities: x ≤ 5 and y ≥ -8.
Solution
The system of linear inequalities provided is:
Step-by-Step Graphing:
-
First Inequality:
- This represents all points to the left of (or on) the vertical line .
- The boundary line will be , a vertical line at , and it will be solid because the inequality includes equality ("≤").
- Shade the region to the left of this line, where .
-
Second Inequality:
- This represents all points above (or on) the horizontal line .
- The boundary line will be , a horizontal line at , and it will be solid because the inequality includes equality ("≥").
- Shade the region above this line, where .
Graph Intersection:
- The solution to this system is the region where both shaded areas overlap.
- This is the area that lies to the left of the line and above the line .
- The lines themselves are included in the solution because both inequalities are non-strict (≤ and ≥).

Here are 5 related questions for you:
- What happens if one of the inequalities had been strict (e.g., or )?
- How do we interpret inequalities when both variables are involved (like )?
- What is the significance of using solid vs. dashed boundary lines in graphing inequalities?
- Can you find the area of the solution region if these inequalities bounded a specific shape?
- How would you approach solving a system of inequalities with more than two conditions?
Tip: Always pay attention to whether the inequality includes equality (≤ or ≥) as it determines whether the boundary line should be solid or dashed.
