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 horizontal position on the coordinate plane.

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 vertical position on the coordinate plane.

Front

How do you write the ordered pair for point C?

Back

The ordered pair for point C is (6, 3).

Front

How do you write the ordered pair for point B?

Back

The ordered pair for point B is (2, 7).

Front

What is the x-coordinate of point C?

Back

The x-coordinate of point C is 6.

Front

What is the y-coordinate of point C?

Back

The y-coordinate of point C is 3.

Front

What is the x-coordinate of point B?

Back

The x-coordinate of point B is 2.

Front

What is the y-coordinate of point B?

Back

The y-coordinate of point B is 7.

Front

If you move 3 units up from point C, what is the new y-coordinate?

Back

The new y-coordinate would be 6 (3 + 3).
