In the Cartesian coordinate plane, how are the quadrants labeled?

In the Cartesian coordinate system, the quadrants are indeed labeled counterclockwise starting from the upper right quadrant. This means that the first quadrant (I) is located where both x and y coordinates are positive, which is at the top right of the plane. Following this, the second quadrant (II) is to the left of quadrant I, where x is negative and y is positive. The third quadrant (III) is below quadrant II, characterized by both x and y coordinates being negative. Finally, the fourth quadrant (IV) is to the right of quadrant III, where x is positive and y is negative. This systematic counterclockwise labeling allows for a clear and consistent understanding of the coordinate system and makes it easier for students to navigate and identify the location of points within each quadrant.
