Aconstant of proportionality can also be considered a(n)
a: unit rate.
b: y-value.
c: x-value.
d: ratio.

A. Unit rate

Step-by-step explanation:

We know that when two variables are proportional, they vary by same constant known as the constant of proportionality.

i.e. If x and y are directly proportional, then we have the relation y = kx where k is any constant known as the constant of proportionality.

Now, as y = kx → .

So, the value of k represents the quotient of y by x.

i.e. the value of k is represented by unit rate, which is the comparison of two quantities combined together.

Hence, the constant of proportionality can be referred as unit rate.

step-by-step explanation:

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
