Coordinate Geometry

Coordinate Geometry

1. Ploting point in a plane (5,4)

   • Step1: draw co-ordinate axis and select units
     • Step2; Starting from origin ,count units on x and y axis
       • Step3: Mark the corresponding points

2. Graph-Linear Equation

   • Step1: Convert given equation in the form y=mx+c
     • Step: Select atleast 3 values of x, such that x,y∈I
       • Step3: Draw table for the ordered pair (x,y)
         • Step4: Plot these ordered points on the graph paper
           • Step5: Draw straight line plotted from straight line

3. Coordinate system

4. Quadrants

   • Plane divided into 4 parts by coordinate axes

5. Cartesian system

   • Two perpendicular lines
     • x axis
       • abscissa
     • y axis
       • ordinate
   • Fixed point
     • Point where x and y axis intersect
       • (0,0)
   • meaning
     • To describe the position of point in a plane
