On the graph of f(x) = 8*sin(3pi*x), points P and Q are at consecutive lowest and highest points with P occurring before Q. Find the slope of the line which passes through P and Q.

Slope = ?

I have tried 48/pi and it didn't work

ymax-ymin=8-(-8)=16
xmax-xmin=1/6-(-1/6)=1/3
(ymax-ymin)/(xmax-xmin)=48
