Why not? Because every math system you've ever worked with has obeyed these properties! You have never dealt with a system where a×b did not in fact equal b×a, for instance, or where (a×b)×c did not equal a×(b×c). Which is why the properties probably seem somewhat pointless to you. Don't worry about their "relevance" for now; just make sure you can keep the properties straight so you can pass the next test. The lesson below explains how I kept track of the properties.

Do I have to do all of them?
Answer:
y = 6
Step-by-step explanation:
I'm assuming you are trying to say slope "0".
If the slope is 0, it means that the general equation Y = mX + c equals to Y = 0x + c and finally Y = c. Since the line is horizontal because it is 0 slope, Y = 6
