The next version of pst-fit (in the next two days) knows the optional
argument "comma":

0.03  2024-03-17  - added option comma for decimals instead of dot

the PS fontsize can be changed by fontscale=20,  (in pt)

\documentclass{article}
\usepackage{pst-fit,pstricks-add}
\begin{document}
\begin{filecontents}[overwrite]{linearbsp.dat}
     5 1
     3 4
     4 2
     6 1
     2 7
\end{filecontents}
\readdata{\Linear}{linearbsp.dat}
\psset{unit=1cm,comma}%%%%%%%%%%%%%%%%%%
\begin{pspicture}(-1,-1)(7,10)
\psaxes[showorigin=false]{->}(0,0)(-1,-1)(7,10)[$x$,270][$y$,0]
\psplot[algebraic,linecolor=gray,linestyle=dashed]{-1}{7}{9-1.5*x}
\listplot[plotstyle=dots,linecolor=red,dotscale=2,dotstyle=x]{\Linear}
\listplot[decimals=6,EqPos=5 6,plotstyle=GLLSR,fontscale=20,%%%%%%%
     linestyle=solid,linecolor=blue,linewidth=1.5pt]{\Linear}
\end{pspicture}
