What are the four quadrants in a coordinate plane?

Back

Quadrant I (Q I): x > 0, y > 0; Quadrant II (Q II): x < 0, y > 0; Quadrant III (Q III): x < 0, y < 0; Quadrant IV (Q IV): x > 0, y < 0.

What is the origin in a coordinate plane?

Back

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

Front

How do you identify the quadrant of a point?

Back

To identify the quadrant, look at the signs of the x and y coordinates: (+,+) for Q I, (-,+) for Q II, (-,-) for Q III, and (+,-) for Q IV.

Front

What does it mean for points to have no relationship in terms of distance from the x-axis?

Back

It means that the points are not equidistant from the x-axis, indicating they are at different heights.
