8 11 12 10 9 7 5 3 9

A. The mean and median will both increase.
B. The mean will increase and the median will decrease.
C. The mean will increase and the median will remain the same.
D. The mean and the median will both decrease.

1. y = mx+b, so plug in your point:
6 = 4*1 + b
...

since 45 is larger than any of the existing values, the mean will rise.
since there are no duplicate values, the median will also rise.
(note that if the two center values were equal, the median might stay the same - why?

2. Thank you! The median might stay the same because they are the same?
