Exploring System of Inequalities

What is a system of inequalities?

• A group of inequalities with different variables

• A group of equations with the same variables

• A group of inequalities with the same variables

• A single inequality with two variables

What does a solution of a system of inequalities represent?

• A line that intersects all inequalities

• A group of ordered pairs that satisfy all inequalities in the system

• A single point that satisfies one inequality

• A single ordered pair that satisfies one inequality
