Front

If the inequality symbol is < or >, the line will be _________.

Back

dotted

Front

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

Back

The symbol is greater than or less than.

Front

Consider the inequality, y < 2x + 3. Which is true?

Back

None of the above.

Front

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

Back

Yes, it is located in the shaded region.

Front

Are the points on the boundary line part of the solution set for y < 2x + 3?

Back

Yes, they are part of the solution set.

Front

What does a solid line represent in graphing inequalities?

Back

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

Front

What does a dotted line represent in graphing inequalities?

Back

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

Front

What is the first step in graphing a linear inequality?

Back

Graph the corresponding linear equation as if it were an equality.

Front

How do you determine which side of the line to shade when graphing an inequality?

Back

Choose a test point not on the line; if it satisfies the inequality, shade that side.

Front

What is the solution set of an inequality?

Back

It is the set of all points that satisfy the inequality.
