Given the linear equation write another linear equation in two variables such that the geometrical representation of the pair so formed is:

(i) intersecting lines

(ii) parallel lines

(iii) coincident lines

(i) Intersecting lines: For this condition,

The second line such that it is intersecting the given line is

2x+4y-6 = 0

As

(ii) Parallel lines:

For this condition,

Hence, the second line can be 4x + 6y - 8 = 0

As

So,

(iii) Coincident lines: For coincident lines,

Hence,

the second line can be 6x + 9y - 24 = 0

So,
