Mini-Unit: Cartesian Coordinate Plane

Front

What is the Cartesian Coordinate Plane?

Back

The Cartesian Coordinate Plane is a two-dimensional plane defined by a horizontal axis (x-axis) and a vertical axis (y-axis), where each point is represented by an ordered pair (x, y).

Front

What are the four quadrants of the Cartesian 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), and Quadrant IV (x > 0, y < 0).

Front

In which quadrant is POINT A located if it is on the y-axis?

Back

POINT A is located in 'No Quadrant' because it lies on the y-axis, where x = 0.

Front

What are the coordinates of a point in Quadrant I?

Back

In Quadrant I, both x and y coordinates are positive, e.g., (3, 2).

Front

What are the coordinates of a point in Quadrant II?

Back

In Quadrant II, the x coordinate is negative and the y coordinate is positive, e.g., (-3, 2).

Front

What are the coordinates of a point in Quadrant III?

Back

In Quadrant III, both x and y coordinates are negative, e.g., (-3, -2).

Front

What are the coordinates of a point in Quadrant IV?

Back

In Quadrant IV, the x coordinate is positive and the y coordinate is negative, e.g., (3, -2).

Front

How do you determine the quadrant of a point given its coordinates?

Back

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

Front

What is the significance of the origin in the Cartesian Coordinate Plane?

Back

The origin is the point (0, 0) where the x-axis and y-axis intersect, serving as the reference point for all other points.

Front

What is the x-axis?

Back

The x-axis is the horizontal line in the Cartesian Coordinate Plane where y = 0.
