The only logical answer is, 2 because the unit rate is value of y when x=1.
y=(1)2
y=2.
As I stated in the same question, the "Unit Rate" is not hard, it's just slope. They are trying to trick you by saying "unit rate". Your unit rate is x2.
We're looking for
such that

Multiplying both sides by
gives us

Notice that when
, the term involving
vanishes and we're left with

Then

so that

Answer:
it is A or D
Step-by-step explanation:
For this case we must factor the following expression:

We take common factor 5:

We have two groups within the parentheses:
Group 1: 
Group 2: 
We factor each group:
Group 1: 
Group 2: 
Rewriting we have:

Answer:
