A permutation is an act of arranging the objects or elements in order. Combinations are the way of selecting objects or elements from a group of objects or collections, in such a way the order of the objects does not matter.

4 songs will be played during assembly but 8 songs were submitted.

The DJ choose 4 songs to play.

n = 8

r = 4

The number of ways the DJ can choose 4 songs from 8 will be

The number of ways the DJ can choose 4 songs from 8 songs is 70.

More about the permutation and the combination link is given below.

I assume, the order matters here.

objects can be chosen out of objects, when the order matters, in ways.

So, the answer is ways.

the slope of the line is 60

one point on the line is (40,10)

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
