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)**

Comparing equation with

and with , we get

We have because

**Therefore, lines have unique solution which means they intersect at one point.**

**(ii) **

Comparing equation with

and with , we get

and

and

We have

Because

**Therefore, lines are coincident.**

**(iii)**

Comparing equation with

and with , we get

and

and

We have

Because

**It means lines are parallel to each other.**
