Use Fit in the definition of a function then use the function as you would 
any other function.

data = Table[7*x + 3 + 10*Random[], {x, 10}];

f[x_] := Evaluate[Fit[data, {1, x}, x]]


    ListPlot[data, PlotStyle -> {AbsolutePointSize[3], RGBColor[1, 0, 0]}], 
    Plot[f[x], {x, 0, 10}, PlotStyle -> RGBColor[0, 0, 1]]];
