Inequalities Symbols and Boundary Points

What happens to the inequality symbol when you multiply or divide by a negative?

• The symbol goes away

• The symbol stays the same

• The symbol is flipped

• Nothing Happens

Two regions created on a graph when separated by a boundary line

• Quadrant

• Half - Plane

• Sides

• Solution

Inequality symbols that create a closed half - plane and all points on the line are included in the solution.

Inequality symbols that create an open half - plane and all points on the line are not included in the solution.

Are the points on the boundary line part of the solution set or not?

• Yes, they are part of the solution set

• No, they are NOT part of the solution set

Are the points on the boundary line part of the solution set or not?

• Yes, they are part of the solution set

• No, they are NOT part of the solution set

Are the points on the boundary line part of the solution set or not?

• Yes, they are part of the solution set

• No, they are NOT part of the solution set

Are the points on the boundary line part of the solution set or not?

• Yes, they are part of the solution set

• No, they are NOT part of the solution set

What does it mean if a point lies on the boundary line of a linear inequality?

• The point satisfies the inequality equation.

• The point is an extraneous solution.

• The point is not part of the solution set.

• The point does not satisfy the inequality equation.
