Simple...
you have: (7,-7) and (6,-5)
Using

to find slope--->>>

=-2
m=-2
Using y=mx+b to find the equation of the line-->>(Use any of the coordinates)
(7,-7)
-7=-2(7)+b
-7=-14+b
-7=-14+b
+14 +14
7=b
y=-2x+7Thus, your answer.
Rate of change
find a2 and a4
a2=27(1/3)^(2-1)=27 times 1/3=9
a4=27(1/3)^(4-1)=27 times 1/27=1
rate of change=(a4-a2)/(4-2)=(1-9)/(4-2)=-8/2=-4
average rate of change is -4
