Study Notes
Linear Inequalities in Two Variables
- The primary focus when dealing with linear inequalities in two variables is to find the region of the coordinate plane that satisfies the inequality.
Comparison with Linear Equations
- Solving linear inequalities in two variables differs from solving linear equations in two variables in that inequalities involve shaded regions, whereas equations involve lines.
Graphing Linear Inequalities
- The purpose of graphing linear inequalities in two variables is to visualize the region of the coordinate plane that satisfies the inequality.
- Graphing linear inequalities helps to visualize the region of the coordinate plane that satisfies the inequality, including the boundary line and the shading.
Problem-Solving
- Solving linear inequalities in two variables allows us to determine the region of the coordinate plane that satisfies the inequality.
- Linear inequalities in two variables can be used to solve problems involving regions, such as determining the area of a region or finding the feasible region for a system of constraints.
- Graphing linear inequalities helps with problem-solving by providing a visual representation of the solution, making it easier to identify the region of interest.
Key Distinctions
