Coordinate Plane Test

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). Each point on the plane is defined by an ordered pair of numbers (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 are coordinates?

Back

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

Front

What does the x-axis represent?

Back

The x-axis is the horizontal line on a coordinate plane where the y-coordinate is zero.

Front

What does the y-axis represent?

Back

The y-axis is the vertical line on a coordinate plane where the x-coordinate is zero.

Front

How do you identify a point in Quadrant IV?

Back

A point in Quadrant IV has a positive x-coordinate and a negative y-coordinate.

Front

What is the distance from a point to the x-axis?

Back

The distance from a point (x, y) to the x-axis is the absolute value of the y-coordinate, |y|.

Front

What is the distance from a point to the y-axis?

Back

The distance from a point (x, y) to the y-axis is the absolute value of the x-coordinate, |x|.

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).

Front

What does it mean for a point to be on the x-axis?

Back

A point is on the x-axis if its y-coordinate is zero, represented as (x, 0).
