Ordered Pairs

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to represent a point in a two-dimensional space, 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 the Cartesian 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 Cartesian plane.

Front

What is the origin in a coordinate system?

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 the coordinates of a point on a graph?

Back

The coordinates of a point on a graph are identified by its position relative to the x-axis and y-axis, expressed as an ordered pair (x, y).

Front

What is the significance of the x-axis?

Back

The x-axis is the horizontal line in a Cartesian coordinate system, where the y-coordinate is zero.

Front

What is the significance of the y-axis?

Back

The y-axis is the vertical line in a Cartesian coordinate system, where the x-coordinate is zero.

Front

How do you plot an ordered pair on a graph?

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 or down along the y-axis.

Front

What is the ordered pair for point B if it is located at x=4 and y=3?

Back

The ordered pair for point B is (4, 3).

Front

If a point is located at (5, -2), what does the negative y-coordinate indicate?

Back

The negative y-coordinate indicates that the point is located 2 units below the x-axis.
