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), where 'x' is the horizontal coordinate and 'y' is the vertical coordinate.

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.

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.

How do you plot an ordered pair on a coordinate plane?

Back

To plot an ordered pair (x, y), start at the origin (0, 0), move 'x' units along the x-axis, and then move 'y' units up (if positive) or down (if negative) along the y-axis.

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

Back

The order in an ordered pair is significant because (x, y) is not the same as (y, x); switching the order changes the location of the point on the coordinate plane.

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).

What are the coordinates of a point in the first quadrant?

Back

In the first quadrant, both coordinates of a point are positive, represented as (x, y) where x > 0 and y > 0.

What are the coordinates of a point in the second quadrant?

Back

In the second quadrant, the x-coordinate is negative and the y-coordinate is positive, represented as (x, y) where x < 0 and y > 0.

What are the coordinates of a point in the third quadrant?

Back

In the third quadrant, both coordinates of a point are negative, represented as (x, y) where x < 0 and y < 0.

What are the coordinates of a point in the fourth quadrant?

Back

In the fourth quadrant, the x-coordinate is positive and the y-coordinate is negative, represented as (x, y) where x > 0 and y < 0.
