16.4 Graphing Number Patterns

Front

What is a coordinate point?

Back

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

Front

What does the first number in a coordinate pair represent?

Back

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

Front

What does the second number in a coordinate pair represent?

Back

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

Front

How do you plot a point on a coordinate grid?

Back

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.

Front

What is the origin in a coordinate grid?

Back

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

Front

What is a number pattern?

Back

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

Front

How do you identify the rule in a number pattern?

Back

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

Front

What is the rule for the pattern: 10, 15, 20, 25?

Back

The rule is to add 5 to each number.

Front

What is an ordered pair?

Back

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

Front

How do you move a point on a coordinate grid?

Back

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