Question

Any two distinct points have exactly two lines that contain them. Explain please? Also is this statement true or false?

Answer 1

One of the early postulates of Euclidean Geometry states that through any two different, there is exactly one line.

Distinct in this case means that the two points are not the same point.

Answer 2

If A and B are two names for the same point, infinitely many lines contain that one point with two names. DISTINCT guarantees that the points are different.
