Across
- 7. A function that can't be represented by a line but often is a curve The rate of change is not constant
- 8. If the ratios of the quantities are equal, than they are proportional
- 11. The raito between all ordered pairs
- 12. A line with an undefined slope x=a
- 14. A line that is decreasing from left to right
- 15. The x-value in a function
- 21. Formed by the intersection of two number lines, the x and y axis.
- 22. a function represented by a line rate of change is constant
- 24. A line with zero slope y=a
- 25. A vertical line
- 27. the set of y-values in the ordered pairs of a relation
- 28. the 4 regions which the x and y axis separated on a coordinate plane
- 29. A relation in which each element of the domain is paired with exactly one element of the range
- 30. A specific relationship in which there is a constant ratio between all ordered pairs.
Down
- 1. The form of a line used to graph the lines
- 2. The x value of an ordered pair, represents the horizontal placement of the point
- 3. The point where the y and x axis intersect on a coordinate plane
- 4. The y value of an ordered pair, represents the vertical placement of the point
- 5. A line that is increasing from left to right
- 6. The vertical line on a coordinate plane
- 9. A ratio that shows how one variable changes with respect to another
- 10. The set of #s, or coordinates written in the form of (x,y)
- 13. a horizontal line
- 16. a set of ordered pairs
- 17. the set of x-values in the ordered pairs of a relation
- 18. If any vertical line passes through the graph of relation no more than once, than it is a function
- 19. The horizontal line on a coordinate plane.
- 20. The y-value in a function
- 23. If the ratios of the quantities are not equal, than they are not proportional
- 26. A ratio that compares the vertical to horizontal change between points
