16.4 Graphing Number Patterns

A coordinate point is a pair of numbers that define a specific location on a grid, usually written as (x, y).

The first number represents the horizontal position (x-coordinate) on the grid.

The second number represents the vertical position (y-coordinate) on the grid.

To plot a point, start at the origin (0,0), move right or left for the x-coordinate, and then move up or down for the y-coordinate.

The origin is the point (0,0) where the x-axis and y-axis intersect.

A number pattern is a sequence of numbers that follow a specific rule or formula.

To identify the rule, look for a consistent operation (like addition or subtraction) applied to each number in the sequence.

The rule is to add 5 to each number.

An ordered pair is a pair of numbers used to locate a point on a coordinate grid, written in the form (x, y).

To move a point, adjust its x-coordinate to move left or right, and adjust its y-coordinate to move up or down.
