how to edit x axis and y axis values?

How to edit these numerical values in the form of variables? for a exapme x1, x2 ......... on the graph

Use the Axis Properties, specifically XTickLabel, YTickLabel, and ZTickLabel to specify them.

x = 1:10;
y = rand(size(x));

figure
plot(x, y)
Ax = gca;
xt = Ax.XTick;
Ax.XTickLabel = compose('x%d',(1:numel(xt)));                   % As Numbers
yt = Ax.YTick;
Ax.YTickLabel = compose('y_{%d}',(1:numel(yt)));                % As Subscripts

Another option is the NumericRuler Properties property TickLabelFormat, however I believe the Axis Properties functions are more appropriate here.

Experiment to get different results.

could you please tell me how to edit the points that only intersect x axis and y axis?

I will do my best, however I have no idea what the desired result is.

One option is to use a legend object to identify the lines, the other is to use text objects for each point of interest.

x = 1:10;
y = rand(size(x));

figure
plot(x, y)
Ax = gca;
xt = Ax.XTick;
Ax.XTickLabel = compose('x%d',(1:numel(xt)));                   % As Numbers
yt = Ax.YTick;
Ax.YTickLabel = compose('y_{%d}',(1:numel(yt)));                % As Subscripts
text(x(1), y(1), sprintf('$$\\ \\leftarrow x=%.2f,\\ y=%.2f$$',x(1),y(1)), 'Horiz','left', 'Vert','middle', 'Interpreter','latex')
text(x(end), y(end), sprintf('$$x=%.2f,\\ y=%.2f\\ \\rightarrow$$',x(end),y(end)), 'Horiz','right', 'Vert','middle', 'Interpreter','latex')

Make appropriate changes to get the desired result.
