I realize your concerns about the on-screen appearance of your line. I have
found a way to make it look straight. Try the following:
Plot[2*x+1,{x,0,10},PlotPoints->2]
One problem with this is that the axes range is changed from your original
Plot[2*x+1,{x,0,10}]
But this appears to give the same axes:
Plot[2*x+1,{x,0,10},PlotPoints->2,PlotRange->{{0,10.2},{0,21.5}}]
You can of course play with the PlotRange to suit your tastes.
I should also point out that the "zig-zag" problem appears to be limited to
the screen display. I printed all three forms and the hardcopy looked very
straight for all of them. Maybe there is some option buried deep in the help
files that I did not feel like spending the time to uncover that will make
the screen version appear "straighter". I tried MaxBend, PlotPoints,
PlotDivision and experimented with Compiled options but none of these seemed
to fix the displayed graph.
