Answer:
B)
and C) 
Step-by-step explanation:
Once a linear function has a constant rate of change, you just have to find the linear functions. Also, the other ones are quadratic functions, and their graph are parabolas, which don't have a constant rate of change.
Considering 
has a constant positive rate of slope 2.

has a constant negative rate of slope -7

It is 7 and I don't know how to explain it.I know it is late,but I hope this helps you.
Answer: D. (-5 < 5)
Step-by-step explanation:
-5 is NOT greater than its opposite (5)
The answer is 2
You multiply both sides by 2 (7y-16=-2)
Then move the constant to the right (7y=-2+16)
Then calculate the sum (7y=14)
The divide both sides by 7
Y=2
