2 questions that I really did not get were these two^^. But once I found out what they were asking, I started to slowly understand it. First and foremost: What does discrete and continuous mean?

The answer is:

Discrete data is counted.

Continuous data is measured.

When looking at the independent variable (x), the discrete variable could be kids in a class because there can’t be half of a student and everyone is unique. Another example is a dice; there are only be 6 possible answers. Continuous data can take any value (within a range) for example time in a race, or the height of my cat. There is an infinite amount of time because there could be 1.5secs, 1.4seconds, 1.345secs etc…
