me figure this out

1b. The graph shows that as age increases short term memory decreases.
1c. Even though the graph predicts and 80 year old woman would have a lower score she may have an exceptionally good memory 

Okay it's been a while so im not 100% on this
a) negative correlation because as age increases memory decreases
b) 1, [rise / run]
c) Lower, it is probably due to different methods of calculation and/or a rare subject
