Answer:
where 
Step-by-step explanation:
This is an arithmetic sequence with the first term is
= -2.7 and has a common difference of
.
Arithmetic Sequence: 
is the nth term and
is the common difference.
The common difference: -2.7, -8.3, -13.9...
Subtract: -2.7- (-8.3) = -5.6, -13.9 - (-8.3) = -5.6
Common difference: 
Recursive rule: 
It represents the slope of the graph
Answer:
C
Step-by-step explanation: Since x is by itself in the first equation, we can substitute 12x + y = 5 into 12(6-y) + y = 5.
