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 x-axis and y-axis?

Back

The x-axis is the horizontal line on a coordinate plane, while the y-axis is the vertical line.

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

What is the origin in a coordinate plane?

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 the coordinate plane?

Back

To identify a point, use its ordered pair (x, y) to move x units along the x-axis and y units along the y-axis.

Front

What is the significance of the point (0,1) on the coordinate plane?

Back

The point (0,1) is located on the y-axis, one unit above the origin.

Front

What is the significance of the point (2,5) on the coordinate plane?

Back

The point (2,5) is located two units to the right of the origin and five units up.

Front

What is the y-coordinate in the ordered pair (4,9)?

Back

The y-coordinate in the ordered pair (4,9) is 9.
