Please help fast Its due tomorrow and I also have school and I need to sleep and it's 11:16.

-6

Step-by-step explanation:

The line passes through (-100,20) and (-80,-100)

Slope = (-100-20) / (-80-(-100))

= (-120) / (-80+100)

= -120/20

= -6

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).
