Answer:
Yes it represents.
Variation tax = 0,25
Explanation:
Direct variation is the name we gave to the rate of change of a first degree function.
A first degree generic function is:
y = f(x) = ax + b
Now observe the question's function:
- x + 4y = -2
4y = x - 2
y = 1/4x - 2/4
y = f(x) = 0,25x - 0,5
0,25 is our constant variation, because any number that x assume will be multiplied by 0,25.
