Answer 1

Explanation:

As these two lines are not parallel so going to intersect at one point so having one solution

Answer 2

A is correct, when two lines have 1 intersection (1 solution).

Explanation:

B Two lines are parallel => No intersection (no solution).

C Two lines are coincident => Many intersection (many solutions).

Hope this helps!
