Graphing Linear Inequalities

Front

What type of line does the inequality y ≥ -2x - 2 represent?

Back

A solid line.

Front

Is the point (3, 1) a solution for the inequality y ≥ -2x - 2?

Back

No, because it is located on the line and the line is dotted.

Front

What does the inequality y ≥ -2x + 1 indicate about the graph?

Back

The graph is a solid line, shaded above.

Front

How can you tell if an inequality will have a solid line?

Back

The symbol has 'or equal to'.

Front

What does a dashed line represent in graphing inequalities?

Back

It indicates that points on the line are not included in the solution.

Front

What does a solid line represent in graphing inequalities?

Back

It indicates that points on the line are included in the solution.

Front

What is the meaning of the inequality symbol '>'?

Back

It means greater than.

Front

What is the meaning of the inequality symbol '<' ?

Back

It means less than.

Front

What does the inequality y < 3 represent on a graph?

Back

A dashed line at y = 3, shaded below.

Front

How do you determine the shaded region for the inequality y > 2x + 1?

Back

Shade above the line y = 2x + 1.
