Across
  1. 3. set of output values
  2. 5. function represented by a corresponding part of domain

  4. 9. ordered pairs are plotted here
  5. 11. type of inequality with two variables
  6. 12. rise to run
  7. 13. a function that resemble a set of stair steps in a graph
  8. 15. variation where y varies directly with value of x
  9. 16. point where line crosses the x axis
  10. 17. mapping or pairing of input values with output values
  11. 18. a set representing a relation
  12. 20. represents function

  5. 6. naming a function "f"
  6. 7. line that lies as close as possible to all data points
  7. 8. type of correlation, where y increases as x increases
  8. 10. an ordered pair is a of an equation
  9. 14. point where line crosses the y axis
