Ordered Pairs

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to locate a point on a grid, written in the form (x, y), where x is the horizontal coordinate and y is the vertical coordinate.

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 grid.

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 grid.

Front

How do you plot the ordered pair (3, 2) on a grid?

Back

To plot (3, 2), start at the origin (0, 0), move 3 units to the right (x-axis), and then move 2 units up (y-axis).

Front

What is the ordered pair for the point located at 4 units right and 5 units up from the origin?

Back

The ordered pair is (4, 5).

Front

If a point is located at (0, 0), what is this point called?

Back

This point is called the origin.

Front

What is the ordered pair for point A if it is located at 2 units left and 3 units down from the origin?

Back

The ordered pair is (-2, -3).

Front

How can you identify the x-coordinate from an ordered pair?

Back

The x-coordinate is the first number in the ordered pair, written as (x, y).

Front

How can you identify the y-coordinate from an ordered pair?

Back

The y-coordinate is the second number in the ordered pair, written as (x, y).

Front

What is the ordered pair for the vertex E if it is at (1, 5)?

Back

The ordered pair for vertex E is (1, 5).
