I don't know that there is a standard way. And as for proper
way, I would say anything that yields the desired result can be
considered proper. In any case, here is one way
data = RandomReal[1, {10, 2}];
f = FindFit[data, m x + b , {m, b}, x];
Plot[m x + b /. f, {x, 0, 1}, Frame -> True, Axes -> None,
Epilog -> {Point[data]},
PlotRange -> {.95 Min@data[[All, 2]], 1.05 Max@data[[All, 2]]}]
