Plot Points on Cartesian Coordinate System Example: Plot the point (2, 3) and identify its position in which quadrant is located. First we will place a dot at the intersection of X and Y axis, which is the center of the Cartesian coordinate and known as the origin. From the origin, move 2 units going right. Our point is […]

  Four Quadrants on a Graph  We know that the two axes X and Y divided the plane into four sections. These four sections are called the Quadrants (one fourth section). The plane is called Cartesian plane or Coordinate plane or the XY plane.  The plural of axis is axes. The quadrants are labelled with Roman numbers […]
