  1. 3. A measure of the steepness of a line
  2. 5. A set of ordered pairs where two lines intersect
  3. 8. A function whose graph forms a straight line
  4. 11. The set of all possible input values (x) of a function
  5. 12. Set of ordered pairs, mapping diagram, table, and graph
  6. 13. A relationship between two variables in which the data do not increase or decrease at the same rate
  7. 17. A function whose graph is not a straight line
  8. 19. The output of a function; a variable whose value depends on the value of the input
  9. 20. Relationship - Is linear, passes through the origin, has a constant of proportionality, written in the form y=mx+b where b=0
  10. 22. A pair of numbers that can be used to locate a point on a coordinate plane
  11. 24. The value put into a function
  12. 25. - The y-coordinate of the point where the graph of a line crosses the y-axis
  13. 26. The value that results from substituting in a given input
  14. 27. The vertical axis on a coordinate plane
  15. 28. A test used to determine whether a relation is a function. If any vertical line crosses the graph of a relation more than once, the relation is not a function

  7. 10. A relationship that has exactly one output for each input
  8. 14. Intercept Form - A Linear equation written in the from y=mx+b, where m represents slope and b represents the y-intercept
  9. 15. The input of a function; a variable whose value determines the value of the output

  11. 18. The horizontal axis on a coordinate plane
  12. 21. Equation - An equation whose solutions form a straight line on a graph
  13. 23. Relationship - Written in the formy=mx+b, where b≠0
