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.
