Front

What type of line is used for inequalities with 'greater than' or 'less than'?

Back

A dotted line.

Front

What type of line is used for inequalities with 'greater than or equal to' or 'less than or equal to'?

Back

A solid line.

Front

In the inequality y < 2x + 3, what does the '<' symbol indicate about the line?

Back

The line will be dotted and shading will be below the line.

Front

Are points on the boundary line included in the solution set for 'less than' or 'greater than' inequalities?

Back

No, they are NOT part of the solution set.

Front

Are points on the boundary line included in the solution set for 'less than or equal to' or 'greater than or equal to' inequalities?

Back

Yes, they are part of the solution set.

Front

What does the inequality symbol '≤' indicate about the line?

Back

The line will be solid.

Front

What does the inequality symbol '≥' indicate about the line?

Back

The line will be solid.

Front

Is (0,0) a solution to the inequality y > -x + 1?

Back

No.

Front

How do you determine if a point is a solution to an inequality?

Back

Substitute the point into the inequality and check if it holds true.

Front

What is the graphical representation of the inequality y < 3?

Back

A horizontal line at y=3, dotted, with shading below.
