No, not in the same plane. But in 3 dimensions it is possible
If the two lines are coplanar, then it is a third, parallel, line which is halfway between the two lines. If the two lines are not in the same plane, then I think it will be a saddle shape (paraboloid).
A function is a mapping between two sets, the domain and the range, such that each element in the domain is mapped to only one element in the range. This is true for all lines in a plane except those that are parallel to the y-axis. Thus, all non-perpendicular lines are functions but vertical lines are not functions.
The Northern and Piccadilly lines are tube lines which have no branches at all.
It is possible to construct an infinite number of lines through any line at a given point. You will not be able to physically draw them, but a filled in circle will all have rays that intersect the line at the same point.
The distance between imaginary lines around the earth parallel to the equator. The relationship is that they all travel from east to west or visa versa.

they are all colonies
It is possible for all nine lines to be perpendicular to at least one other line.

What are relationships in dance? Is that the question? If it is then the relationship may be between the dancers on the stage, the relationship between the audience and the dancer, and the relationship between the dancer and the choreographer. All of which are important for a dancer to perform their best.
It all depends on the girl.
Yes, in relationships, in neighborhoods, in parks, in simple vicinity; all is possible and happens all of the time.
Not usually. Most relationships in which they don't fight at all, they aren't interested in the relationship anymore, however it is possible but only if you agree with everything :)
