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).

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

Which axis runs vertically on a graph?

Back

The Y-axis runs vertically.

Front

Which axis runs horizontally on a graph?

Back

The X-axis runs horizontally.

Front

How do you write the ordered pair for the point located at (3, 4)?

Back

The ordered pair is written as (3, 4), where 3 is the x-coordinate and 4 is the y-coordinate.

Front

If a point is located at (0, 5), what is its x-coordinate?

Back

The x-coordinate is 0.

Front

If a point is located at (4, 0), what is its y-coordinate?

Back

The y-coordinate is 0.

Front

What is the ordered pair for point A if it is located at (2, 3)?

Back

The ordered pair for point A is (2, 3).

Front

How do you find the distance between two points (1, 2) and (4, 6)?

Back

Use the distance formula: d = √((x2 - x1)² + (y2 - y1)²).
