COORDINATE GEOMETRY

COORDINATE GEOMETRY

1. Quadrants

   • Plane divided into 4 parts by Coordinate Axis

2. Cartesian System

   • To describe position of points in a plane
   • Two perpendicular line
     • X-axis
       • X Coordinate
         • Abscissa: Perpendicular distance from Y axis
     • Y-axis
       • Y coordinate
         • Ordinate: Perpendicular distance from x axis
     • Fixed Point: Origin
       • Point where x and y axis intersect O(0,0)

3. Steps of marking a Point on a graph

   • Step 1: Draw coordinate axis and select unts
   • Step 2: Starting from the origin, count units on x and y axis
   • Step 3: Mark the corresponding points

4. Graph-linear equation
