Coordinate Planes

Front

What is a coordinate plane?

Back

A coordinate plane is a two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis).

Front

What are the axes in a coordinate plane?

Back

The x-axis (horizontal) and the y-axis (vertical) are the two axes in a coordinate plane.

Front

What is an ordered pair?

Back

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

Front

What does the first number in an ordered pair represent?

Back

The first number in an ordered pair represents the x-coordinate, which indicates the position along the x-axis.

Front

What does the second number in an ordered pair represent?

Back

The second number in an ordered pair represents the y-coordinate, which indicates the position along the y-axis.

Front

How do you write an ordered pair?

Back

An ordered pair is written in the form (X, Y).

Front

In the ordered pair (3, 7), what is the x-coordinate?

Back

The x-coordinate is 3.

Front

In the ordered pair (3, 7), what is the y-coordinate?

Back

The y-coordinate is 7.

Front

What is the origin in a coordinate plane?

Back

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

Front

How do you identify a point on a coordinate plane?

Back

To identify a point, use its ordered pair (x, y) to find its position on the x-axis and y-axis.
