Coordinate Plane and Quadrants

Front

What is the coordinate plane?

Back

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 the coordinate plane?

Back

Quadrant I (positive x, positive y), Quadrant II (negative x, positive y), Quadrant III (negative x, negative y), Quadrant IV (positive x, negative y).

Front

What is an ordered pair?

Back

A pair of numbers (x, y) that represent a point on the coordinate plane.

Front

What does the point (0,0) represent?

Back

The Origin, where the X-axis and Y-axis intersect.

Front

How do you identify the quadrant of a point with positive x and negative y coordinates?

Back

It is located in Quadrant IV.

Front

How do you identify the quadrant of a point with negative x and positive y coordinates?

Back

It is located in Quadrant II.

Front

What are the coordinates of Point A if it is located in Quadrant I?

Back

Any ordered pair (x, y) where x > 0 and y > 0.

Front

What are the coordinates of Point B if it is located in Quadrant III?

Back

Any ordered pair (x, y) where x < 0 and y < 0.

Front

What is the significance of the X-axis?

Back

It is the horizontal line on the coordinate plane where y = 0.

Front

What is the significance of the Y-axis?

Back

It is the vertical line on the coordinate plane where x = 0.
