Study Notes
Systems of Linear Inequalities
- Ordered pairs must satisfy all inequalities in the system to be part of the solution set.
- Example of a valid ordered pair: (2,2) meets the criteria for the inequalities y > 1/2 x and y < -3x + 3, and y > 2x - 2.
Inequality Evaluation
- Ordered pair (-2, 2) satisfies the inequalities y < -x + 1 and y > x.
- The number 2 is crucial in completing the system represented by y < -2x - 1 and another inequality.
Specific Ordered Pairs
- The pair (3,0) is valid for the inequalities y > -2x + 3 and y < x - 2.
- Another valid pair (4,0) satisfies the conditions y < 3x - 1 and y > -x + 4.
Graphical Representations
- A graph can illustrate the constraints y < 1/3x - 1, y 2/3x + 3, and y < -1/3x + 2.
- Systems represented by a graph can include multiple inequalities, like y > 1/3 x + 3 and 3x - y > 2.
- Example graph systems: x - 5y < -5 and y < -2x - 4, or x + 5y > 5 and y < 2x + 4.
No Solution Scenarios
- An ordered pair falling into no valid solution zone occurs when y > x - 1 and y < x - 1, resulting in no solution.
Summary of Ordered Pairs and Inequalities
- Graphs identify valid pairs and systems, e.g., (3,5) satisfying y < 5x + 2 and y > x + 1.
- Systems often consist of linear inequalities that delineate regions on a graph where solutions can be found.
