coordinate grid

Front

What is a coordinate grid?

Back

A coordinate grid is a two-dimensional space defined by a horizontal axis (x-axis) and a vertical axis (y-axis) where points are identified by ordered pairs (x, y).

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

In the ordered pair (x, y), which number represents the x-coordinate?

Back

The first number, x, represents the x-coordinate.

Front

In the ordered pair (x, y), which number represents the y-coordinate?

Back

The second number, y, represents the y-coordinate.

Front

What is the x-axis?

Back

The x-axis is the horizontal line on a coordinate grid where the y-coordinate is zero.

Front

What is the y-axis?

Back

The y-axis is the vertical line on a coordinate grid where the x-coordinate is zero.

Front

What is the origin in a coordinate grid?

Back

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

Front

How do you identify a point on a coordinate grid?

Back

A point is identified by its coordinates, written as an ordered pair (x, y).

Front

What does the point (3, 4) represent on a coordinate grid?

Back

The point (3, 4) represents a location 3 units right and 4 units up from the origin.

Front

What is the distance between the points (2, 3) and (2, 5)?

Back

The distance is 2 units, as they are on the same vertical line.
