1. CARTESSIAN SYSTEM

   • Cartesion system ina plane is a coordinate system that specifies each point uniquely by a pair of numerical coordinates5
     • CARTESIAN PLANE
       • A Cartesian Plane is defined by two perpendicular number lines , the x-axis which is Horizontal and Y axis which is Vertical
         • Cartesian Plane
           • Coordinate Plane
             • XY plane
           • Quadrant
           • Coordinates
       • Plotting of Points on the Cartesian Plane
         • How to locate (3,5) in the cartesian plane ?
           • The coordinates of the point (3,5) tell us that the distance of this point
             • From the y-axis along the positive x-axis is 3 units
               • From the x-axis along the positive y-axis is 5 units
                 • From origin 0 we count 3 units and mark A on x-axis
                   • From origin 0 we count five units and make B on y-axis
                     • Now join the two lines nd the intersection point is p(3,5).
