Coordinate Plane Practice

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 (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 the x-axis?

Back

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

Front

What is the y-axis?

Back

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

Front

How do you determine the quadrant of an ordered pair?

Back

By examining the signs of the x and y coordinates: (+,+) in Quadrant I, (-,+) in Quadrant II, (-,-) in Quadrant III, and (+,-) in Quadrant IV.

Front

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

Back

The coordinates will have a y-value of 0, e.g., (3, 0).

Front

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

Back

The coordinates will have an x-value of 0, e.g., (0, 4).

Front

What is the origin in the coordinate plane?

Back

The point where the x-axis and y-axis intersect, represented as (0, 0).

Front

What is the significance of the signs of coordinates in determining the quadrant?

Back

The signs indicate the location of the point relative to the axes, helping to identify the quadrant.

Front

If a point has coordinates (-4, 3), in which quadrant is it located?

Back

Quadrant II.
