I slammed on the brakes to avoid an accident and noticed no power, so I pulled over and car was not running and now it won't start.

Shut off and will not start after slamming on brakes?

Hello CORTEZ EDWARDS,
My thought is that you may have possibly damaged the brake booster. There is a hose that goes to it. This provides engine vacuum to control your power assist for the brakes.
I would remove that hose, have an assistant put their thumb over it and try turning the vehicle over and see if it starts.
If there is an issue with the brake booster it can create a massive vacuum leak which could make the air/fuel mixture in the engine too lean to ignite.
Since the issue happened right after you had to slam on the brakes, I would try that first.
I will add a picture of the location of this hose for you.
Here is an article that will help aid in a no start condition:

Let me know how it goes or if I can help further.
Thank you,
Brendon
