1. Cross multiplication method

2. Substitution method

3. Elimination method

4. PAIR OF LINEAR EQUATION IN TWO VARIABLES

   • General form
     • a1X+b1Y+c1 =0
     • a2x + b2y+c2=0
     • Where a1,b1,c1=Real numbers =a2,b2,c2
   • Solution graphically
     • Each solution (X,Y), corresponds to a point on the line representing the equation and vice versa
   • Graphically representation
     • Infinitely many solution
       • Coinciding lines
     • No solution
       • Parallel lines
     • Unique solution
       • Intersecting lines
   • Equations for:-
     • X-axis: y=0
     • Y-axis :x=0
     • Line parallel to the x-axis : y=constant
     • Line parallel to Y- axis: x= constant
