If five points are collinear, are the coplanar?

Question

If five points are collinear are they coplanar? Is the question. I think the answer is no but Im not sure and I need help fully understanding the question

Answer 1

Yes, the five points are coplanar. The line they lie on is part of a infinite number of planes.

 

However, it will be impossible to identify a single plane to which they belong, as a line can be on many planes.

Answer 2

Three points determine a plane. If five points are collinear then any three of the points determine the same plane as any other three points.
