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.
