Math Problem Statement
2x + 3y > -5
Solution
To solve the inequality , we can represent it graphically or analyze it algebraically.
Step-by-step process:
-
Rewrite the inequality to express it as an equation first: This is the boundary line for the inequality, which we'll use to determine the solution region.
-
Find the intercepts:
- When , solve for :
- When , solve for :
-
Graph the boundary line:
- Plot the intercepts at and .
- Draw the line. This line represents the equation .
- Since the original inequality is strict (using ), the line should be dashed, indicating that the points on the line are not included in the solution.
-
Determine the region:
- Select a test point (such as the origin, ).
- Substitute into the inequality:
- This is true, so the region containing the origin is the solution set for the inequality.
Final Answer:
The solution to is the region above the dashed line .
