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 (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

How do you identify the coordinates of a point?

Back

Coordinates of a point are identified as an ordered pair (x, y), where 'x' represents the horizontal position and 'y' represents the vertical position on the coordinate plane.

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

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

How do you determine which quadrant a point is in?

Back

To determine the quadrant, look at the signs of the x and y coordinates: Quadrant I (both positive), Quadrant II (x negative, y positive), Quadrant III (both negative), Quadrant IV (x positive, y negative).

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to locate a point on the coordinate plane, written in the form (x, y).

Front

What are the coordinates of point E if it is located at (0, 2)?

Back

The coordinates of point E are (0, 2), meaning it is on the y-axis, 2 units above the origin.

Front

What is the significance of the signs of coordinates?

Back

The signs of coordinates indicate the location of the point in relation to the axes: positive x and y are in Quadrant I, negative x and positive y in Quadrant II, etc.
