First one is B second one is C third is A last is B
gradient or slope=<u>y2 -y1</u>
x2 - x1
so for A, p is x1 and 3 is y1..
For B, 6 is x2 and p is y2
2= <u>p - 3</u>
<u> </u><u> </u><u> </u><u> </u><u> </u>6 - p
2 ( 6 - p) = p - 3
12 - 2p = p - 3
-2p + p = -3 - 12
-p = - 15
p = 15
There are 8 weeks and 18 books. therefore you would multiply these numbers together.
the answer would be 144 different combinations.
not sure about the permutation or combination notation, but I got you on the first part!
