Unsolvable because there is no factor for 13
Answer:
(D) 
Step-by-step explanation:
Two variables x and y are proportionally related if they can be written in the form y=kx, where k is the constant of proportionality.
From the given options, if 
(B)
is of the form y=kx
(C)
is of the form y=kx with as 
in its lowest form.
(C)
is of the form y=kx with as 
in fractional form.
On the Contrary,
In Option D, does not represent a proportional relationship between x and y. The constant of proportion is supposed to be a product of x.

We know that
a
=

,
b
=
−
8
and
c
=
2
, so let's substitute:
k
=

.
So, we have
min
=

. Let's check:
graph{(x^2 - 8x + 2 - y)(-14 -y)=0 [-11.82, 20.22, -15.38, 0.64]}
