• x>0,y>0

in Q2

• x<0,y>0

in Q3

• x<0,y<0

in Q4

• x>0,y<0

Answer 2

A. The x-coordinate is positive and the y-coordinate is positive.

Explanation:

The Cartesian plane is divided into four regions by the x-axis and y-axis.

These regions are called "quadrants".

Quadrant I is the top right region, where x and y coordinates of points are positive.

From here, move in a counterclockwise direction.

Therefore, Quadrant II is the top left region, where the x-coordinate is negative and the y-coordinate is positive.

Quadrant I → (x, y)

Quadrant II → (-x, y)

Quadrant III → (-x, -y)

Quadrant IV → (x, -y)
