How to add string and number to a graph?

I would like to add the value of the estimated slope to my graph, but I don't know which command to use.

This is what I've tried

% slope
hold on
text(['slope = ',num2str(b)]);

% and

% slope
hold on
txt = ['slope = ',num2str(b)];
text(b,txt,'VerticalAlignment','Cap');

text(x,y,"slope = "+(b))
%    ^-^----- x and y coordinates

Hi, thanks!

But what I was actually looking for is the text not depending on any point, sort of as a legend where you can move the box around. I have quite a few data points so the string depending on one of them looks "in the way" if that makes sense...

Do you have any other suggestion for that? thanks

Put that information in the title of the axes or as the string in the legend for the line in question?

You can move text objects around after they are plotted. Select the "edit plot" arrow, select the text object, and drag it around the screen. But Matlab still needs to know where to initially plot the text so you have to use the x,y inputs to text.

You could put it in the corner of a plot like this

text (min(xlim), max(ylim), 'Upper Left Corner')

str = 'hello'
gtext(str) % put the text interactively using your mouse
