Start = 0; % sorry I completely misinterpreted the question xD
End = 1;
Point = 260;
plot(linspace(Start, End, 1e2), repelem(Point, 1e2), '--r')
text(End - .11, Point + .07, 'Ground', 'Color', 'r')

It's not really necessary to plot 100 points along the line. The first and last points are enough, as in:
plot([0,1],[260,260],'--r');
