Coordinate Plane

Front

What is the coordinate plane?

Back

A two-dimensional surface formed by the intersection of a horizontal number line (x-axis) and a vertical number line (y-axis).

Front

What are the four quadrants of the 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 origin in the coordinate plane?

Back

The point where the x-axis and y-axis intersect, represented as (0, 0).

Front

What does the x-axis represent?

Back

The horizontal number line in the coordinate plane where y = 0.

Front

What does the y-axis represent?

Back

The vertical number line in the coordinate plane where x = 0.

Front

What are ordered pairs?

Back

A pair of numbers (x, y) that represent a point in the coordinate plane.

Front

How do you identify the quadrant of a point?

Back

By checking 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 type of integers are located to the right of the origin on the x-axis?

Back

Positive integers.

Front

What type of integers are located to the left of the origin on the x-axis?

Back

Negative integers.

Front

If a point has coordinates (3, -2), where is it located?

Back

In Quadrant IV, because x is positive and y is negative.
