Chapter 8 Vocab Drake

4. A number plane; a plane in which a coordinate system has been set up
8. The slope of a line that falls from left to right
9. The intersection of the axis on a number plane. The zero point on each axis.
11. rise over run
14. a correspondence between two sets, the domain and range, the assigned to each member of the domain exactly one member of the range
17. Points that lie on the same line
18. A vertical line that has a denominator of 0
21. x coordinate; starts with a d
22. y coordinate; starts with a r
24. The slope of a line that rises from left to right
25. The value that is placed into a function, typically represented by the variable X
26. A notation involving an arrow used to define a function
27. The first coordinate in an ordered pair of numbers; the X coordinate

1. The horizontal number line in a number plane; the X axis
2. The Y coordinate of a point where a graph intersects the Y axis. Since the point is on the Y axis it’s X coordinate zero.
3. A variable that stands alone and does not rely on the value of any other variable to determine its value
5. The second coordinate in an ordered pair of numbers; the Y coordinate
6. The result or value produced by a function based on a given input
7. The vertical number line in a number plane; the Y axis
10. A straight horizontal line going across a graph
12. A notation involving and = used to define a function
13. The X coordinate of the point where a line crosses the X axis
15. An equation whose graph is a line
16. Lines in the same plane that do not intersect lines with the same slope in different Y intercepts
19. A variable whose value is determined by the value of another variable
20. A pair of numbers for which the order of the numbers is important
23. one of the four regions into which the coordinate axis separate a number plane
