I have a black line on a layer. How can I replace it with a dotted red line?

I'm a newbie, please make it simple. I assume it goes like this: ensure dotted line is defined, change colour to red, select solid line, replace with selected line type.

===============
Something to keep in mind when working with GIMP. It is NOT a CAD (vector) program by default. It is a RASTER program and it makes dots (pixels) change color, etc... Also, by default, the dots are in a 1 thick by X wide by Y high matrix. 'Lines' are not really existent in raster, just dots on, dots off.

The usual solution has long been to zoom way in and change the desired pixels, one at a time.

Just what you didn't want to hear. :(

OOPs - forgot to reply all. Sorry.

How about a select by shape and colour and replace black with red?

He wanted to get a dotted red line, maybe select and fill with a pattern?

=====================
by shape - seems to not be a part of Gimp 2.2 Using the magic wand can (with conditions) be useful, replacing selected area's color via bucket works but creating dash pattern takes more effort than just zooming in and coloring the breaks by hand. Agreed - I'm not up to date on Gimp versions but loading a ton of programs I don't use just to compile and use Gimp is not in line with my mentality. "Portions of this program are taken from the following ..." constitutes valid copyright notice, at least last time I asked. Putting them with the GIMP branch makes updates much easier too. Each becomes a whole unto itself, rather than causing conflicts. That thing about write it once and use it often works for cut and paste too. Usually takes less space to boot.

Back on corrections - any way that works for the user is valid. And Yes - it is nice to have the needed tools 'pre-built' and available. But - when all else fails.... :)
