Front

What does the inequality y > 2x - 4 represent in a graph?

Back

The region above the line y = 2x - 4.

Front

What does the inequality y < 2 represent in a graph?

Back

The region below the horizontal line y = 2.

Front

How do you determine if a point is a solution to a system of inequalities?

Back

Substitute the point into each inequality and check if all inequalities are satisfied.

Front

What is the solution set of a system of linear inequalities?

Back

The set of all points that satisfy all inequalities in the system.

Front

What does it mean if a line is dashed in a graph of an inequality?

Back

The points on the line are not included in the solution set.

Front

What does it mean if a line is solid in a graph of an inequality?

Back

The points on the line are included in the solution set.
