An ordered pair is a pair of numbers used to locate a point on a coordinate plane.
First number (x-coordinate, domain) tells you to move horizontally
Second number (y-coordinate, range) tells you to move vertically

How far a number is from zero. (replace negative numbers)

The y-intercept of this line is the value of y at the point where the line crosses the y axis.

Discrete numbers can only take certain values.

A set of data is said to be continuous if the values belonging to the set can take on ANY value within a finite or infinite interval.

If an equation shows a relationship between x and y in which the value of y is dependent upon the value of x, y is known as the dependent variable and is sometimes referred to as 'function(x)' or f(x).

# data[].attributes.body
A variable in an equation that may have its value freely chosen without considering values of any other variable.

The range is the set of all second elements of ordered pairs (y-coordinates).
Example: (3, 2) -- range is 2.

# data[].attributes.body
The domain is the set of all first elements of ordered pairs (x-coordinates).
Example: (3, 2) -- domain is 3.
