A school club tracked how many posters they hung and how many students signed up. The scatter plot shows a positive linear association. Two representative points are marked:

(2, 18)

and

(8, 54)

, where

x

is posters and

y

is sign-ups. Estimate the slope of a reasonable line of best fit (in sign-ups per poster).
