In the (x, y) coordinate plane, the axes split the plane into four sections, called quadrants. We label them I, II, III, IV with Roman Numerals. The upper right most quadrant is Quadrant I, where both x and y are positive. The upper left is Quadrant II, where x is negative and y is positive. The lower left is Quadrant III where both x and y are negative, and the lower right is Quadrant IV where x is positive and y is negative. You can see that the quadrants numbers go in a counter-clockwise direction.
