Anyone know any of these

I'm surprised to inform you that yes, yes I do.

Step-by-step explanation:

If you didn't know, all those lines stand for something. Stand for an equation.

For example, let's take the first line shown, question number 5.

The line moves down on the number line, going from 4 all the way down to -6.

Since the dot is filled in, that means that the line includes 4, which means our answer's greater than or lesser than sign should have a line under it, meaning "or equal to".

A is the only reasonable answer for question 5, because it reads "X (which you could substitute for any point in the blue line) is less than or equal to 4."

If we use what we learned from question 5 for the next 3 questions, we could rightly say that the answer to 6 is D, the answer to 7 is C, and the answer to 8 is B.

If I'm wrong on any of these, feel free to scream profanities. Wouldn't be the first time.
