Coordinate Geometry

Coordinate Geometry

1. Step 1: Draw co-ordinate axis and select unit

   • Step 2: Starting from origin, count units on x and y axis
     • Step 3: make the corresponding points

2. Plain divided into 4 parts by co-ordinate axes

   • Quadrants

3. Plotting point in a plain (5,4)

4. Cartesian System meaning

   • Fixed point
     • Point where x and y axis intersect O(0,0)
     • Two Perpendicular lines
       • x axis is called Aabscissa
       • y axis is called Ordinate
   • To describe the position of point in a plane

5. Coordinate System

6. Graph-Linear Equation

   • Step 1: Convert given equation in the form y = mx + c
   • Step 2: Select at least 3 values of x, such that x , y = 1
   • Step 3: Draw table for the ordered pair (x , y)
   • Step 4: Plot these ordered points on the graph paper
   • Step 5: Draw straight line passing through plotted points
