Topics in Coordinate Geometry

1

The Cartesian Plane – Building the Framework

  • Two perpendicular number lines are drawn on a plane – one horizontal and one vertical.
  • The horizontal line is called the x-axis (also written as X'X).
  • The vertical line is called the y-axis (also written as Y'Y).
2

Coordinates of a Point – Abscissa and Ordinate

  • Every point in the Cartesian plane is described by an ordered pair of numbers (x, y) called its coordinates.
  • The x-coordinate (abscissa) is the perpendicular distance of the point from the y-axis, measured along the x-axis.
  • The y-coordinate (ordinate) is the perpendicular distance of the point from the x-axis, measured along the y-axis.
3

Signs of Coordinates in Different Quadrants

  • Quadrant I: Both x and y are positive → (+, +). Example: (3, 5)
  • Quadrant II: x is negative, y is positive → (−, +). Example: (−4, 2)
  • Quadrant III: Both x and y are negative → (−, −). Example: (−3, −7)
4

Plotting Points on the Cartesian Plane – Step-by-Step

  • Step 1: Draw the x-axis (horizontal) and y-axis (vertical) intersecting at origin O.
  • Step 2: Mark equal units on both axes.
  • Step 3: To plot point (a, b) – start at origin, move 'a' units along x-axis (right if positive, left if negative).
