Coordinate Plane Practice

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). It is used to locate points using ordered pairs (x, y).

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 is the x-axis?

Back

The x-axis is the horizontal line on a coordinate plane where the y-coordinate is zero. It runs left to right.

Front

What is the y-axis?

Back

The y-axis is the vertical line on a coordinate plane where the x-coordinate is zero. It runs up and down.

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 coordinates (0, 0).

Front

How do you identify the quadrant of a point?

Back

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

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 first number in a coordinate pair represent?

Back

The first number in a coordinate pair represents the x-coordinate, which indicates the horizontal position.

Front

What does the second number in a coordinate pair represent?

Back

The second number in a coordinate pair represents the y-coordinate, which indicates the vertical position.

Front

What is the distance from the origin to the point (3, 4)?

Back

The distance is 5 units, calculated using the Pythagorean theorem: √(3² + 4²) = √(9 + 16) = √25 = 5.
