Question

Write about lines and its coondition when they are intersecting parallel and coincident

Answer 1

when lines are intersecting parallel and coincident they are equal and equation of the other line is a multiple of any real number k.

ex. 2x-3y=7 & 6x-9y=21 & x-3y/2=7/2 etc. are parallel and coincident.

when they are just parallel ,only the constant term changes in the equation.
ex. 2x-3y=7 & 2x-3y=8 & 6x-9y=5 etc are parallel.
