Hello Murray,
How about this:
f[{x_, y_}] := {2 x + 1, y + 2};
DynamicModule[{pt1 = {1, 1}}, {LocatorPane[Dynamic[pt1],
Framed@Graphics[{}, PlotRange -> {{0, 5}, {0, 5}}, Axes -> True]],
Framed@Graphics[{}, PlotRange -> {{0, 5}, {0, 5}}, Axes -> True,
Epilog -> {PointSize[Medium], Dynamic@Point[f[pt1]]}]}]
