If you could keep the salt in there yes, the problem is that it washes out as soon as you put it in there so no it would not keep roots out of the sewer line.
No.
No, there is root killer available that is copper sulfate crystals. It is supposed to kill the roots and not hurt the tree.
The estimated cost of a new sewer line repairs would run you about $5500.00 dollars. It will keep the sewer and your toilets running smoothly without any clogging.
You may have roots that have penetrated your sewer line. If you have a septic system it may be time for pumping and an inspection of your system. I am going with tree roots breaking into your sewer line though.
Yes, but make absolutely certain that you check your city/town/local ordinances as to what can be flushed into the line. Some municipalities do not permit flushing certain chemicals (hazardous) into a sewer line.

Root damage can cause extensive damage to your home itself. Once the sewer lines have been compromised, many problems can occur within the home. The water supply can be interrupted and floor drains and toilet can back up, potentially causing flooding or damage to appliances. No type of sewer line is immune to roots. Clay pipes, the most common kind of pipe in older water and sewer systems, are the most susceptible to root damage. Roots will penetrate any crack, hole, or poorly sealed joint in a sewer line. Concrete and PVC pipes are less susceptible to root intrusion but are not root-proof. Once roots penetrate the line, they can exert considerable pressure on the pipe, which then must be repaired or replaced.

The obvious and main problem (and reason to keep your sewer lines clean) is because a backed-up sewer line means that sewage can get backed up into sinks and bathtubs. This is unsanitary and a health hazard. A broken sewage line is costly to repair.
