#(Delta y)/(Delta x)=-1#

Explanation:

Plug in #x=-8#

#f(-8)=64-72+18=10#

Plug in #x=-2#

#f(-2)=4-18+18=4#

Now plug it into the average rate of change formula. The average rate of change formula is #(Delta y)/(Delta x)=#(change in y) / (change in x):

#(Delta y)/(Delta x)=(10-4)/(-8-(-2))#

#(Delta y)/(Delta x)=-1#
