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 indicates the horizontal position on the coordinate plane.

Front

What does the second number in an ordered pair represent?

Back

The second number represents the y-coordinate, which indicates the vertical position on the coordinate plane.

Front

How do you plot an ordered pair on a coordinate plane?

Back

Start at the origin (0,0), move along the x-axis to the x-coordinate, and then move vertically to the y-coordinate.

Front

What are the coordinates of the point located 3 units right and 2 units up from the origin?

Back

(3, 2)

Front

What are the coordinates of the point located 4 units left and 5 units down from the origin?

Back

(-4, -5)

Front

If a point has coordinates (0, 5), where is it located?

Back

It is located on the y-axis, 5 units above the origin.

Front

If a point has coordinates (5, 0), where is it located?

Back

It is located on the x-axis, 5 units to the right of the origin.
