Ordered Pairs

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 represents the x-coordinate, which shows how far to move left or right from the origin.

Front

What does the second number in an ordered pair represent?

Back

The second number represents the y-coordinate, which shows how far to move up or down from the origin.

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

What is the x-axis?

Back

The x-axis is the horizontal line on a coordinate plane where the y-coordinate is 0.

Front

What is the y-axis?

Back

The y-axis is the vertical line on a coordinate plane where the x-coordinate is 0.

Front

How do you find the location of a point given its ordered pair?

Back

To find the location, start at the origin, move along the x-axis to the x-coordinate, and then move up or down to the y-coordinate.

Front

What is the location for the point (2, 8)?

Back

The location for the point (2, 8) is 2 units right and 8 units up from the origin.

Front

What is the location for the point (7, 4)?

Back

The location for the point (7, 4) is 7 units right and 4 units up from the origin.

Front

What is the coordinate that is vertical?

Back

The coordinate that is vertical is the y-coordinate.
