THE MATH.

4. if any vertical line posses through the graph or the relation no more than once, then it is a function.
5. a specific relationship in where there is a constant ratio between all ordered pairs.
7. a function represented by a line rate of the change is constant
9. a line that is decreasing from left to right.
10. the ratio between ordered pairs
12. if the ratios of the quantities are equal then they are proportional
14. if the ratios of the quantities are not equal then they are not proportional
15. the form of the line used to graph the line.
16. the x-value within a function.

1. a ratio that shows how one vertical changes with respect to another.
2. the y-value within a function.
3. a line with zero slope y=a
6. a line with an undefined slope x=o
8. a relation in which element of the domain is paired within one element of the range.
9. a function that cannot be represented by a line but often is a curve the rate on change is NOT constant.
11. a vertical line
12. a line that is increasing from left to right.
13. a horizontal line.
