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 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

What is the origin in a coordinate plane?

Back

The origin is the point where the x-axis and y-axis intersect, represented by the ordered pair (0, 0).

Front

How do you identify a point on a coordinate plane?

Back

To identify a point, use its ordered pair (x, y) where 'x' is the horizontal distance from the origin and 'y' is the vertical distance from the origin.

Front

What is the x-axis?

Back

The x-axis is the horizontal line on a coordinate plane where the y-coordinate is 0.

Front

What is the y-axis?

Back

The y-axis is the vertical line on a coordinate plane where the x-coordinate is 0.

Front

How do you plot an ordered pair (3, 4)?

Back

To plot (3, 4), move 3 units to the right on the x-axis and 4 units up on the y-axis.

Front

Which ordered pair represents a point in the first quadrant?

Back

Any ordered pair where both x and y are positive, such as (2, 3).

Front

What is the distance between the points (2, 3) and (2, 5)?

Back

The distance is 2 units, as they are vertically aligned on the same x-coordinate.
