Sam has five favorite football teams, and every week, he puts their flags on his flagpole in random order a. in a given week, how many different ways can he arrange the flags? b. if he only has room for three of the flags on his flagpole, how many different ways can they be arranged?

A. This is an example of a situation making use of the concept of Fundamental Principles of Counting. On the first spot, Sam may choose from the five available flags. On the next spot, he can only choose from four flags. This goes on until no more flag is left. For short, there are 5! ways. This is equal to 120.

b. Since only 3 out of the five flags can be used and the arrangement is important, make use of Permutation. The answer is 5P3 = 60. There are 60 ways. 

I’m pretty sure the slope would be 1 since the x and y values increase by 1
