what is the first quadrant on a graph
Quadrant (plane geometry) These are often numbered from 1st to 4th and denoted by Roman numerals: I (where the signs of the (x,y) coordinates are (+,+)), II (−,+), III (−,−), and IV (+,−). When the axes are drawn according to the mathematical custom, the numbering goes counter-clockwise starting from the upper right ("northeast") quadrant.
