Infinite number of lines pass through a single point

We can see a point A. Five different lines are drawn from this point A. AB, AC, AD, AE and AF. We can draw an infinite number of lines passing through this single point A.
Questions to think about 1. Move the points B, C, D, E and F and think how many lines are possible from this single point A? 2. When two different points A and B are given, then how many lines are possible which pass through these two points?
