Across
  1. 5. The rate of change; how steep a line is.
  2. 9. A mathematical statement that compares expressions using symbols such as >, <, ≥, or ≤.
  3. 10. A set of two or more linear equations with the same variables.
  4. 14. Used when the inequality symbol is > or < because the boundary line is not included in the solution.
  5. 15. An equation written as y = mx + b, where m is the slope and b is the y-intercept.
  6. 16. The process of coloring the region that represents all solutions to the inequality.
  7. 17. The two equations have the same slope and the same y-intercept.
Down
  1. 1. The value is larger than or equal to another value.
  2. 2. The two equations have different slopes.
  3. 3. The two equations have the same slope but different y-intercepts.
  4. 4. The value is larger than another value.
  5. 6. The value is smaller than or equal to another value.
  6. 7. The point where two lines cross; this represents the solution of the system.
  7. 8. The value is larger than or equal to another value.
  8. 11. A point used to check which side of the boundary line satisfies the inequality (often (0,0)).
  9. 12. Used when the inequality symbol is ≥ or ≤ because the boundary line is included in the solution.
  10. 13. The point where the line crosses the y-axis.
