  1. 2. A filled-in circle used on a number line. It shows that the value is included in the answer.
  2. 4. A broken line used when the edge is not 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 circle used on a number line. It shows that the value is not included in 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 the comparison true. It can be shown on a graph or written in notation.
  7. 16. A continuous line used when the edge is part of the answer. It appears with comparisons that include equality.
  8. 18. A comparison that makes a straight-line boundary on a graph. It shows all the answers on one side of the line.
