This is slopes— what is ( -11, -2 ) ( -15 , -18 ) ?

m = 4

Step-by-step explanation:

The slope of two given points are:

We are given the points of (-11, -2) & (-15, -18).

The slope of the line is 4.

Hope this helps.

2,3

Step-by-step explanation:

You can track the probabilities using different case, i.e. Anty gets to 0 after 1 steps, 2 steps, 3 steps, and so on.  This gives us e_1 = 1/2*1 + 1/4*2 + 1/8*3 + 1/16*4 + ... By arithmetico-geometric series, e_1 = 2.  Similarly, e_2 = 1/2*2 + 1/4*3 + 1/8*4 + 1/16*5 + ... = 3, so (e_1,e_2) = (2,3)
