Understanding Ordered Pairs and Quadrants

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, written in the form (x, y), where 'x' is the horizontal coordinate and 'y' is the vertical coordinate.

Front

What are the four quadrants in a Cartesian plane?

Back

The four quadrants are: Quadrant I (x > 0, y > 0), Quadrant II (x < 0, y > 0), Quadrant III (x < 0, y < 0), Quadrant IV (x > 0, y < 0).

Front

Where is the origin located on a Cartesian plane?

Back

The origin is located at the point (0, 0), where the x-axis and y-axis intersect.

Front

What does the x-coordinate represent in an ordered pair?

Back

The x-coordinate represents the horizontal position of a point on the Cartesian plane.

Front

What does the y-coordinate represent in an ordered pair?

Back

The y-coordinate represents the vertical position of a point on the Cartesian plane.

Front

How do you determine the quadrant of a point with coordinates (x, y)?

Back

To determine the quadrant, check the signs of x and y: Quadrant I (both positive), Quadrant II (x negative, y positive), Quadrant III (both negative), Quadrant IV (x positive, y negative).

Front

What is the location of the point (-4, 0)?

Back

The point (-4, 0) is located on the x-axis, 4 units to the left of the origin.

Front

What is the location of the point (0, 4)?

Back

The point (0, 4) is located on the y-axis, 4 units above the origin.

Front

What is the location of the point (2, 2)?

Back

The point (2, 2) is located in Quadrant I, 2 units right and 2 units up from the origin.

Front

What is the location of the point (-2, -4)?

Back

The point (-2, -4) is located in Quadrant III, 2 units left and 4 units down from the origin.
