  1. 3. a function that can be written in the form 𝑦 = 𝑚𝑥 + 𝑏, where 𝑚 and 𝑏 are real numbers; consists of a set of ordered pairs all lying on the same line
  2. 7. to cause a change in something; to make a difference; to influence
  3. 12. a relation in which the quotient of the dependent and independent variables remains constant
  4. 13. the difference between consecutive terms of an arithmetic sequence; always constant
  5. 14. the set of output values corresponding to the domain values
  6. 15. a sequence in which the difference between any two consecutive terms is constant
  7. 17. the variable in a function that represents the input values; the first coordinate in the ordered pairs
  8. 18. in a relation, the relationship between the change in the dependent value and the change in the independent value
  9. 19. the variable in a function that represents the output values; the second coordinate in the ordered pairs
  10. 20. formula the formula used to generate the terms of a recursive sequence
  11. 21. the form of a relation that is written as 𝑦 = 𝑚𝑥 + 𝑏, where 𝑚 and 𝑏 are real numbers, 𝑚 is the slope, and 𝑏 is the 𝑦-intercept of the line
  12. 22. quality of a relation in which the dependent variable increases as the independent variable increases
  13. 23. the value of the quotient of the dependent and independent variables in a direct variation

  1. 1. quality of a relation in which the dependent variable decreases as the independent variable increases
  2. 2. the output of a function when the input is zero
  3. 4. a formula that gives the nth term of a sequence directly
  4. 5. the set of input values for which the function is defined
  5. 6. the point on a graph at which the graph crosses the y-axis
  6. 8. a slope that occurs when all the values of the independent variable are the same; the slope of a vertical line
  7. 9. a slope that occurs when all the values of the dependent variable are the same; the slope of a horizontal line
  8. 10. in a function, the ratio of the change in the dependent value with respect to the change in the independent value
  9. 11. the form of a linear relation that is 𝑦 – 𝑦1 = 𝑚(𝑥 – 𝑥1 ), where 𝑚 is the slope and (𝑥1, 𝑦1) is a point on the line
  10. 16. to be an example or expression of something
