Answer:
B
Step:
The general equation for linear is y=mx+b
So all is linear except B
Some of the possible points using this equation are...
(2,14)
(1,10)
(0,6)
(-1,2)
(-2,-2)
The answer will be 0;7 and 2;112.
Answer:
Third option. 
Step-by-step explanation:
For this exercise you need to remember one of the properties for exponents.
There is a property called the "Negative property of exponents" which states the following:
Where 
As you can observe,
is the reciprocal of 
In this case you have the following expression given in the exercise:

Observe the expression. As you can notice, the base "n" has a negative exponent, which is -6.
Therefore, applying the Negative property of exponents explained at the beginning of this explanation, you can simplify the expression.
Then, the simplified form of
is the one shown below:

It's ....c 8000 lbs because there is 2000 lbs in a ton so you do 4x2 which equals 8 then you add your 3 zeros. Hope I was able to help.
