Question

For what condition of solution, lines are parallel?​

Answer 1

If two lines are parallel then, they have no solution pair of linear equations is inconsistent; If two lines are coincident then, they have infinite solution and pair of linear equations is consistent; If two lines are intersecting then, they have unique solution and pair of linear equations is consistent.

Answer 2

Answer ❣️-----

If the two lines are parallel, the angle between them and the positive side of x-axis will be equal. The figure given below illustrates the above situation. (v) Condition for the lines to be parallel in terms of the perpendicular distance between them.
