3. Graphical Method:
The graph of a pair of linear equations in two variables is represented by two
(1) If the lines intersect at a point, then that point gives the unique solution
equations. In this case, the pair of equations is consistent.
(ii) If the lines coincide, then there are infinitely many solutions
line being a solution. In this case, the pair of equations is dependent (co
(ii) If the lines are parallel, then the pair of equations has no solution. In thi
pair of equations is inconsistent.
