See below

Explanation:

Collinear: points are collinear if all of them are in the same straight line

Coplanar: points are coplanar if all of them are in the same PLANE

Two points are allways collinear. This is the simpliest way to draw a line.
Three points in space are allways coplanar, but not necesarily collinear.
