On comparing the ratios and find out whether the lines representing the following pairs of linear equations intersect at a point, are parallel or coincident:

(i)



(ii)



(iii)


i) Comparing these equation with

=


=


We get,


=


=


Hence,


=


We find that,


Therefore, both lines intersect at one point.


ii) Comparing these equations with ,


=


=


We get,


=


=


Hence,


=


We find that,


=


Therefore , both lines are coincident.


iii) Comparing these equations with,


=


=


We get,


=


=


Hence,


=


We find that,


=


Therefore, both lines are parallel.
