Max is given the graph of the linear inequality 3x - 7.2y < 0 and asked to determine whether a given point is a solution. She notices that the point falls on the boundary line of the graph. What should she conclude?

Question

• The point is a solution to the linear inequality because points on boundary lines are only solutions when the inequality symbol is > or <.
• The point is not a solution to the linear inequality because points on boundary lines are only solutions when the inequality symbol is ≥ or <.
• The point is a solution to the linear inequality because points on boundary lines are always solutions to linear inequalities.
• The point is not a solution to the linear inequality because points on boundary lines are never solutions to linear inequalities.

Answer 1

The correct answer is:

• The point is not a solution to the linear inequality because points on boundary lines are only solutions when the inequality symbol is ≥ or <.
