The Coordinate Plane

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), used to locate points using ordered pairs.

Front

What are the four quadrants of the coordinate plane?

Back

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 is an ordered pair?

Back

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

Front

How do you identify the location of a point in Quadrant III?

Back

In Quadrant III, both x and y coordinates are negative.

Front

What are the coordinates of a point located on the x-axis?

Back

The y-coordinate is 0, so the coordinates are of the form (x, 0).

Front

What are the coordinates of a point located on the y-axis?

Back

The x-coordinate is 0, so the coordinates are of the form (0, y).

Front

What does the point (0, 0) represent?

Back

The origin, where the x-axis and y-axis intersect.

Front

How do you plot the point (3, -2) on the coordinate plane?

Back

Move 3 units to the right on the x-axis and 2 units down on the y-axis.

Front

What is the significance of the x-axis?

Back

The horizontal line in the coordinate plane where y = 0.

Front

What is the significance of the y-axis?

Back

The vertical line in the coordinate plane where x = 0.
