**Ignore?**

Set

A collection of distinct objects/A collection of "things" (objects or numbers, etc).

Element

An object in a set/Members of a set

Relation

When two things are connected/ A function

Ordered Pair

Two numbers in order, for example (2,4); Two numbers written in a certain order. Usually written in parentheses like this: (4,5)

Arrow Diagram

Used to represent a relation

Domain

The set of first elements of a relation/All the values that go into a function

Range

The set of second elements associated with the first elements (domina) of a relation/ The set of all output values of a function.

Function

A relation where each element in the first set is associated with exactly on element in the second set/a special relationship where each input has a single output.

Independent Variable

A variable whose value is not determined by the value of another variable, and whose value determines the value of another variable/An "input" value of a function.

Dependent Variable

A variable whose value is determiend by the value of another variable/The "output" value of a function.

Function Notation

Notation used to show the independent variable in a function.

Origin

The point where the horizontal axis and the vertical axis intersect

Coordinates

The numbers in an ordered pair that locate a point on a coordinate grid (same as ordered pair)

Vertical Line Test

A visual way to check if a graph shows a function

Rate of Change

The change in one quantity with respect to the change in another quantity (also called a slope)

Linear Relation

A relation that has a straight-line graph

Label

Noun: a word or number used to describe one specific part of a graph Verb: to put a label somewhere

Scale

Numbers written on the axis How much you increase between each mark on the graph

Plot

To put data (information) onto a graph

Cartesian Plane

A 2-dimensional, flat surface. The plane has two mutually axes that meet, at right angles, at a point which is called the origin.

Coordinate

Also called ordered pairs, we write them in the format (x, y)

x-axis

The horizontal axis (left/right)

y-axis

The vertical axis (up/down)

origin

(0,0)

Linear Function

A linear relation whose graph is not a vertical line

Y – intercept

The y-coordinate of a point where a graph intersects the y-axis

X – intercept

The x-coordinate of a point where a graph intersects the x-axis
