Area under ALL probability distribution curves is 1.0, because all possible outcomes are taken into account.
The nth term is 6n+4 and the 40th term is 244
The price it 2 years would be 10k cash
Slope = (-7+4) / (7-1) = -3/6 = -1/2
using point (1,-4)
equation y + 4 = -1/2(x - 1)
answer is C.
y + 4 = -1/2(x - 1)
