- GENERAL FORM :
a1x+b1y+c1=0 ,
a2x+b2y+c2=0
where a1,b1,c1 and
a2,b2,c2 are all real
numbers
- SOLUTION
GRAPHICALLY : Each
solution (x,y)
corresponds to a point
on the line representing
the equation and
vice-versa
- ALGEBRIC METHODS
- Elimination method :
- Cross-multiplication method
- Substitution method
- Graphical
Representation
- The co-efficients a
and b should not be
equal to 0 .
