A filled-in dot on a number line represents that the point is included in the set or interval being represented. It indicates that the value at that point is part of the solution set or range being considered. In interval notation, a filled-in dot is used to show that the endpoint is included in the interval, whereas an open dot is used to indicate that the endpoint is not included.
