About NCERT Solutions for Class 9 Maths Chapter 3 Coordinate Geometry

Coordinate geometry includes three exercises which are based on the following topics. Revise them thoroughly before you start practising the NCERT exercises of this chapter. 

• Coordinate geometry is a branch of mathematics that helps in presenting geometric figures in a two-dimensional plane. 
  • The plane that divides the space into two dimensions is known as a cartesian plane or coordinate plane. 
  • The horizontal line on the cartesian plane is called the x-axis, and the vertical line is called the y-axis.
• The point of intersection of the axes is called the origin.
• There are four quadrants in the cartesian plane, the values of which are: 
  • I quadrant: (+x, +y)
  • II quadrant: (-x, y)
  • III quadrant: (-x, -y)
  • IV quadrant: (x, -y)
• The distance of a point from the y-axis is called its x-coordinate, or abscissa, and the distance of the point from the x-axis is called its y-coordinate, or ordinate.
• If x ≠ y, then (x, y) ≠ (y, x), and (x, y) = (y, x), if x = y.
• The coordinates of a point on the x-axis are of the form (x, 0) and that of the point on the y-axis are (0, y).
