Question: dots and curve fitting plot together

how can i plot 20 pairs of (x,y) data,displaying both dots and one of available commands of CurveFitting Package in one diagram? for example if we have L:=[1,2,...,20]: and w:=[23,24,25,...,42]: plot dots:[1,23],[2,24],...,[20,42](but without writing these 20 pairs manual!) together with a fitting line in one diagram.
