1. State the quadrant for each of these points in Cartesian plane






f) (



We know the quadrant signs are given below

  • We require two perpendicular axes to locate a point in the plane. One of them is horizontal and other is Vertical
  • The plane is called Cartesian plane and axis are called the coordinates axis
  • The horizontal axis is called x-axis and Vertical axis is called Y-axis
  • The point of intersection of axis is called origin.
  • The distance of a point from y axis is called x — coordinate or abscissa and the distance of the point from x — axis is called y — coordinate or Ordinate
  • The x-coordinate and y — coordinate of the point in the plane is written as (X, y) for point and is called the coordinates of the point
  • The Origin has zero distance from both x-axis and y-axis so that its abscissa and ordinate both are zero. So the coordinate of the origin is (0,0)
  • A point on the x — axis has zero distance from x-axis so coordinate of any point on the x-axis will be (X, 0)
  • A point on the y — axis has zero distance from y-axis so coordinate of any point on the y-axis will be (0, Y)
  • The axes divide the Cartesian plane in to four parts. These Four parts are called the quadrants
  • The coordinates of the points in the four quadrants will have sign according to the below table
We Know the Quadrant Signs Are Given Below
1st Quadrant++
2nd quadrant-+
3rd quadrant--
4th quadrant+-

So we can easily find the quadrant for each of these points
