Warm-up: Plotting and naming points

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.

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

In which quadrant is the ordered pair (2, 5) located?

Back

Quadrant I, where both x and y coordinates are positive.

Front

What are the four quadrants of a coordinate plane?

Back

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

What is the ordered pair of point A if it is located at (0, 6)?

Back

(0, 6) is the ordered pair for point A.

Front

What is the ordered pair of point E if it is located at (5, 2)?

Back

(5, 2) is the ordered pair for point E.

Front

What is the x-coordinate in the ordered pair (8, 2)?

Back

The x-coordinate is 8.

Front

What is the y-coordinate in the ordered pair (2, 8)?

Back

The y-coordinate is 8.

Front

How do you identify the quadrant of an ordered pair?

Back

Determine the signs of the x and y coordinates: both positive in Quadrant I, x negative and y positive in Quadrant II, both negative in Quadrant III, and x positive and y negative in Quadrant IV.

Front

What is the significance of the x-axis in a coordinate plane?

Back

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