Okay, I'm going to assume that the part you're confused about is the part about how to use the number line to get the answer since the answer is given to you (it's -3).

So what you want to do is plot a point on -7. Since the line ends at -5, extend the line by drawing 2 vertical lines about to represent -6 and -7 (if you're reading it from left to right the -7 would come before -6 because it is a smaller value). Then you would want to hop 4 lines to the right, starting on -7. You would land on -3 which is the answer.

A random sampling is simply referred to as a subset of individuals that are picked from a larger set of individuals.

With regards to the question, Jim wanted to find out what the audience thought about the debate and after the event, he stood at the exit to survey every fifth guest.

This means that it was a random sampling and anyone could have been picked, the sampling wasn't bias.
