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,
