Here are a couple of ways:

First generate some data and a fitted curve

data = Sort@RandomReal[10, 10];
f = m x + b /. FindFit[data, m x + b, {m, b}, x];

Then create the plot

Plot[f, {x, 0, 11},
  Epilog -> {PointSize[.015], Point[Transpose@{Range[10], data}]}]

Note, if the data were a 2D array the Epilog portion would have been

{Pointsize[.015],Point[data]}

or

Show[ListPlot[data], Plot[f, {x, 0, 11}]]
