  1. 3. f(x), used to represent the output of the function f for an input of x.
  2. 6. The x-coordinate of the point where the line crosses the x-axis.
  3. 9. A relation in which each element of the domain is paired with exactly one element of the range.
  4. 12. One of the two regions on either side of the line separating a coordinate plane.
  5. 13. A pattern of change that is true of most of the data.
  6. 14. Lines in the same plane that do not intersect.
  7. 15. The value k in an equation of direct variation for which y = kx. A constant ratio of two variables related proportionally.

  2. 2. A linear equation expressed in the form of ax + by = c, where a, b, and c are real numbers and a and b are not both equal to 0.
  3. 4. A correlation that occurs when the y-coordinates decrease as the x-coordinates increase.
  4. 5. The y-coordinate of the point where the line crosses the y-axis.

  8. 11. A line that separates a coordinate plane into half-planes.
  9. 14. An equation of a line written in the form of y-y=m(x-x) where on ordered pair of x, y is a point on the line and m is the slope.
  10. 17. A correlation that occurs when the y-coordinates increase as the x-coordinates increase.
  11. 19. An equation that describes a function.
  12. 20. The pairing of the domain and range, or x-coordinate and y-coordinate.
