Sense you would like it explained than the question is asking how many otter box Defender Covers where shipped in that price. So when you have that they want the amount of Otter Box Defenders than you divide the amount paid for the shipment with the amount of the otter box defender price.
I hope this is helpful.
Answer:
One order pair is
(
2,0)
Step-by-step explanation:
What ordered pairs are the options?
Pick a value for
x
and solve for
y
. Or find the intercepts.
If
x
=
2
, then:
y
=
2
−
2
⇒
y
=
0
So we have
(
2
,
0
)
If
x
=
0
, then:
y
=
0
−
2
⇒
y
=
−
2
Here we have
(
0
,
−
2
)
You can simply use
0
for both
x
and
y
(intercept) to get the same answer.
When 
, we have
and of course 3 | 6. ("3 divides 6", in case the notation is unfamiliar.)
Suppose this is true for 
, that
Now for 
, we have
so we know the left side is at least divisible by 
by our assumption.
It remains to show that
which is easily done with Fermat's little theorem. It says
where 
is prime and 
is any integer. Then for any positive integer 
,
Furthermore,
which goes all the way down to
So, we find that
