There are many ways to properly tie a knot for a fishhook. A normal way is very simple and takes little time to learn. The line that I preferred to buy, along with some hooks that I will link below to buy. You want to focus on trying to buy a hook that would fit in the fishes mouth. For example, you do not want to use a shark hook for a largemouth mass in a pond. Some places offer hooks that say what fish they are for, and even some places like a Bass Pro Shop will offer a kit where the knot is already attached to the hook so you do not have to tie them. Also, there is a tool that you can buy that is able to almost make the knot for you in seconds which is very good so you are not spending a lot of time trying to tie a knot and can get out there and catch some fish!
This link here will link you to a website that explains the different types of knots.
