Parallel lines - these are lines that are equidistant to each other but will never meet.
Asymptotic lines - this is an imaginary line that the graph will become closer and closer but still they can't even touch each other.
Intersecting lines - these are pair of lines that intersect or at one point they meet each other but once you extend the lines they will never meet again. At some point they become as one but not destined to each other 💔💔💔
1 and 2 lines can't even touch each other😥
