Ordered Pairs

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to represent a point in a coordinate system, typically 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 a graph.

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 a graph.

Front

How do you identify the coordinates of a point on a graph?

Back

To identify the coordinates of a point, locate the point's position on the graph and read the corresponding X and Y values.

Front

What is the coordinate of point A if it is located at (3, 7)?

Back

The coordinate of point A is (3, 7), where 3 is the X-coordinate and 7 is the Y-coordinate.

Front

How do you write the coordinates of a point located at X=5 and Y=2?

Back

The coordinates of the point are written as (5, 2).

Front

What is the significance of the order in an ordered pair?

Back

The order in an ordered pair is significant because (X, Y) is different from (Y, X); the first number always represents the X-coordinate.

Front

If a point is located at (8, 5), what is its X-coordinate?

Back

The X-coordinate of the point (8, 5) is 8.

Front

If a point is located at (4, 4), what is its Y-coordinate?

Back

The Y-coordinate of the point (4, 4) is 4.

Front

What is the coordinate of point B if it is located at (6, 6)?

Back

The coordinate of point B is (6, 6), where 6 is both the X-coordinate and the Y-coordinate.
