Final answer:
An open circle on a graph indicates that the number is a solution to the inequality, and it is true.
Step-by-step explanation:
The statement is true. An open circle on a graph indicates that the number is a solution to the inequality. In an inequality graph, an open circle is used to represent values that are not included in the solution set. This is in contrast to a closed circle, which is used to represent values that are included in the solution set.
