Coordinate Planes and Quadrants

Front

What is a coordinate plane?

Back

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

Front

What are the four quadrants of a coordinate 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

What are coordinates?

Back

Coordinates are a set of values that show an exact position on a coordinate plane, usually written as (x, y).

Front

What does the x-coordinate represent?

Back

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

Front

What does the y-coordinate represent?

Back

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

Front

In which quadrant is the point (3, -5)?

Back

The point (3, -5) is in Quadrant IV.

Front

In which quadrant is the point (-2, 4)?

Back

The point (-2, 4) is in Quadrant II.

Front

What is the y-coordinate of the point (7, 5)?

Back

The y-coordinate of the point (7, 5) is 5.

Front

What is the x-coordinate of the point (-1, -1)?

Back

The x-coordinate of the point (-1, -1) is -1.

Front

How do you identify the quadrant of a point?

Back

To identify the quadrant, check the signs of the x and y coordinates: (+, +) for Quadrant I, (-, +) for Quadrant II, (-, -) for Quadrant III, and (+, -) for Quadrant IV.
