Functions

1. The point at which a line intercepts the y-axis. Where x=0.
3. function whose graph is not connected by a line and is defined only for a set of numbers that can be listed, such as the set of whole numbers or the set of integers.
5. The value going into the function.
9. variable is a function of the independent variable.
10. The resulting value from the function.
12. When the rate of change varies from point to point.
15. Inputs are paired with outputs using (x,y) ordered pairs, tables, or mapping diagrams.
18. An equation whose solutions form a straight line on a coordinate plane.
24. A relationship between two quantities in which the ratio of one quantity to the other quantity is constant.
27. function whose graph is a connected line because the indendent variable can be any real number.
29. Slope-intercept form of a linear equation where the y-intercept is identified first.

2. A slope that rises as the line is read from left to right.
4. variable that stands alone and is not dependent on another variable.
6. A ratio of the change in the independent variable to the corresponding change in the dependent variable.
7. rate A rate in which the second quantity in the comparison is one unit. Also known as slope.
8. A mathematical rule written using symbols.
11. A constant ratio of two variables related proportionally.
13. A ratio of the change in the y variable to the change in the x variable. Ideal when calculating slope when a graph is given.
14. pair A set of two numbers in which the order has an agreed up meaning.
16. The change in x-coordinates. Calculated as x2-x1.
17. A slope that does not remains flat as the line is read from left to right.
19. A relation that pairs each independent input from the domain with exactly one dependent output from the range.
20. equation of a linear function written as y=mx+b or y=b+mx.
21. The set of all independent/input (x) values in a relation.
22. A set of data that is made up of two paired variables.
23. The change in y-coordinates. Calculated as y2-y1.
25. A slope that falls as the line is read from left to right.
26. The set of all dependent/output (y) values in a relation.
28. Slope-intercept form of a linear equation where slope is identified first.
