Math Problem Statement
Solution
Let’s analyze the graph and the inequalities step by step.
-
Line A:
- The slope of Line A is negative (downward slope). Using two points from the graph, the slope is because it goes down unit for every unit to the right.
- The -intercept of Line A is (where the line crosses the -axis).
- The shaded region below Line A indicates the inequality is .
-
Line B:
- The slope of Line B is positive (upward slope). Using two points from the graph, the slope is because it rises units for every unit to the right.
- The -intercept of Line B is (where the line crosses the -axis).
- The shaded region above Line B indicates the inequality is .
-
Shaded Region:
- The shaded region is the overlapping solution area that satisfies both inequalities.
Final Inequalities:
- Line A:
- Line B:
