Answer:
Step-by-step explanation:
we are given
y varies directly as x
so, we can write equation as
where
k is constant of proportionality
We have
at x=-1 , y=6
so, we can use it to find k
so, we get
now, we can plug it back
now, we can plug x=5
and we get
Option C: -3 is the average rate of change between and
Explanation:
The formula to determine the average rate of change is given by
Average rate of change =
We need to find the average rate of change between and
Thus, from the table, we have,
,
,
Thus, substituting these values in the formula, we get,
Average rate of change =
Thus, the average rate of change between and
is -3.
Hence, Option C is the correct answer.
