  1. 2. A filled-in dot used on a number line. It shows that the value is included in the answer.
  2. 4. A broken boundary used when the edge does not count as part of the answer. It appears with comparisons that do not include equality.
  3. 10. A symbol that shows a value is no more than a certain amount. It includes the boundary in the answer.
  4. 13. A hollow dot used on a number line. It shows that the value is not part of the answer.
  5. 14. A way to mark all the points that make the comparison true. It shows the solution area on the graph.
  6. 15. All the values that make a comparison true. It can be written in different forms or shown on a graph.
  7. 16. A continuous boundary used when the edge counts as part of the answer. It appears with comparisons that include equality.
