I had a plumber over and he ran a camera into the drain line in my slab. It showed a spot where the cast iron drain line has corroded out on the botton of the drain pipe... He quoted 10,000 dollars to bust up slab and replace that portion of drain line..... it is located under our formal Dining Room.... Is there any other method to fix this line without busting up my slab

The first question I would ask him is why that particular spot is rusted out? If the entire line is cast iron and on a continuous slope, wouldn't finding one spot where the bottom rusted out mean the entire line is in a similar condition only that spot is the first of many to come?

You might be able to have the pipe lined, you might be able to tunnel underneath the floor to access the pipe for repair, or you might be able to abandon that pipe and reroute a new one although some removal of the floor would likely be required.
We can't discuss pricing here but if you opt to go for bursting up the floor I think getting a couple more estimates would be in order.

You can also tunnel under the house depending where you are. I am in South Florida with fairly shallow and sandy soil so tunnel under is an option.
Several years ago I replaced about 25' of pipe under the house. Here is the thread with pics.
