23 Questions

1.
A function where the rate of change is NOT constant

2.
An interval with two endpoints

3.
The values belonging to a set that can take on any value within a given range

4.
The y-coordinate of a point where a line crosses the y-axis

5.
A coordinate system formed by the intersection of a horizontal number line, called the x-axis, and a vertical number line, called the y-axis

6.
The set of the first numbers (inputs, x-coordinates) of the ordered pairs in a relation

7.
An interval unbounded at one or both ends

8.
The steepness of a line on a graph, equal to its vertical change divided by its horizontal change (rise over run)

9.
y= mx + b, where m is the slope and b is the y-intercept of the line

10.
A variable (often denoted by y ) whose value depends on that of another

11.
The x-coordinate of the point where the line crosses the x-axis

12.
A function with a constant rate of change; a straight line

13.
The values belonging to a set that are unconnected, separate, distinct points

14. The set of second numbers (outputs, y-coordinates) or the ordered pairs in a relation

15.
An ordered set or list of numbers

16.
A test to determine if a relation is a function: if a vertical line drawn passes through two or more points, the relation is NOT a function.

17.
The point at which two lines meet and cut across each other

18. A set of pairs of input and output values

19.
Ax + By = C, where A, B, and C are not decimals or fractions, where A and B are not both zero, and where A is not a negative

20.
A pair of numbers that give the location of a point on the coordinate plane; (x, y)

21.
y - y1 = m(x - x1), where m is the slope and x1, y1 is an ordered pair located on the line

22.
A relationship from one set (called the domain) to another set (called the range) that assigns to each element of the domain exactly one element of the range

23.
A variable (often denoted by x ) whose variation does not depend on that of another
