4.2.1b Coordinate Plane2

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 does the x-axis represent?

Back

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

Front

What does the y-axis represent?

Back

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

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 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

How do you identify the coordinates of a point?

Back

The coordinates of a point are identified by its position relative to the x-axis and y-axis, expressed as (x, y).

Front

What is the coordinate pair for point A located at 3 units right and 2 units up from the origin?

Back

The coordinate pair for point A is (3, 2).

Front

What is the coordinate pair for point B located at 4 units left and 5 units down from the origin?

Back

The coordinate pair for point B is (-4, -5).

Front

What quadrant is point C located at (-3, 4)?

Back

Point C is located in Quadrant II.
