Front

What type of line is used when graphing an inequality with the symbols < or >?

Back

A DOTTED line is used.

Front

What type of line is used when graphing an inequality with the symbols ≤ or ≥?

Back

A SOLID line is used.

Front

What does the inequality y ≥ -x - 1 represent in a graph?

Back

It represents the region above the line -x - 1, including the line itself.

Front

What does the inequality y < x + 4 represent in a graph?

Back

It represents the region below the line x + 4, not including the line.

Front

Which ordered pair is a solution to the inequality y > -x - 1?

Back

Any point above the line -x - 1, such as (0,0).

Front

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

Back

Substitute the point into each inequality; if it satisfies all, it is a solution.

Front

What is the solution set of the system y > 2x - 4 and y < 2?

Back

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

Front

What does it mean if a point lies on a dashed line in a graph of an inequality?

Back

The point is NOT included in the solution set.

Front

What does it mean if a point lies on a solid line in a graph of an inequality?

Back

The point IS included in the solution set.

Front

What is the graphical representation of the inequality y < -x + 1?

Back

The region below the line -x + 1, not including the line.
