Chris, this is probably something you just have to learn. In general the vipers and pit-vipers have live birth, but not all of them, there are a few that lay eggs.
Snakes like garter snakes and water snakes have live birth, as do some small fossorial snakes.
The rest tend to be egg layers.
You will run into a lot of discussions about the advantages and disadvantages of a snake laying eggs verses having live birth.
For instance, if you have a female rattlesnake carrying her young untill they are born, the young gain protection by being inside a large, protective snake. But, if someone or something kills the female, then they have also killed all of the young.
If a snake layes eggs somewhere, and the female is killed, well the eggs will still hatch out. The disadvantage of a snake that hatches from an egg is that it will be smaller, and easier prey for animals that might eat it, and there is no protection from its mother.

Another large classification that gives live birth would be the boas. Although it's a bit more primative version, it's effectively the same.
The pythons on the other hand, lay eggs.
There may also be some exceptions to these two, but I can't think of any offhand.
