Answer:
Negative linear association.
Step-by-step explanation:
To solve this equation we must first plug in 5 for x.

<span> (5 - 4x)
</span>↓

(5 - 4 · 5)
The next step would be to multiply 4 by 5 to get rid of the parenthesis within our main parenthesis.

(5 - 4 · 5)

(5 - 20)
The next step would be to subtract both of the numbers within the parenthesis.

-

· 15 = -

-

Now we simplify our answer to get our final answer.
-5
