How do you plot multiple best fit lines to one graph?

I have one graph and need to plot two best fit lines on it and find where they intersect. I can plot one best fit line but I don't know how to plot two on the same graph. Is there any way to do this?

Thanks.

Can you provide the code? Without more information, maybe this helps you

On cftool, you can open new fits for the same data in new tabs. So ... no, not on the same figure.

But .. you can save the fitted models and outputs to workspace and plot on same figure.
