Across
- 3. f(x), used to represent the output of the function f for an input of x.
- 6. The x-coordinate of the point where the line crosses the x-axis.
- 9. A relation in which each element of the domain is paired with exactly one element of the range.
- 12. One of the two regions on either side of the line separating a coordinate plane.
- 13. A pattern of change that is true of most of the data.
- 14. Lines in the same plane that do not intersect.
- 15. The value k in an equation of direct variation for which y = kx. A constant ratio of two variables related proportionally.
- 16. If every vertical line that intersects a graph intersects that graph in exactly one point, then the graph represents a function.
- 18. The set of all possible output values or y-coordinates.
- 21. A lack of an obvious or predictable trend that connects two data sets.
- 22. An equation written in the form of y = mx + b, where m is the slope and b is the y-intercept.
- 23. The description of the relationship between two data sets.
- 24. The rate of change between any two points on a line; the ratio of vertical change to horizontal change.
- 25. A table of ordered pairs that represent solutions of a function.
- 26. Intersecting lines at a right angle.
Down
- 1. The additive inverse of the multiplicative inverse of a number.
- 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.
- 4. A correlation that occurs when the y-coordinates decrease as the x-coordinates increase.
- 5. The y-coordinate of the point where the line crosses the y-axis.
- 7. A set of ordered pairs.
- 8. The set of all possible input values of a function.
- 10. A graph of ordered pairs that represent solutions of a function.
- 11. A line that separates a coordinate plane into half-planes.
- 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.
- 17. A correlation that occurs when the y-coordinates increase as the x-coordinates increase.
- 19. An equation that describes a function.
- 20. The pairing of the domain and range, or x-coordinate and y-coordinate.
