Is c= e/-4 a direct variation, inverse variation, or neither?

See Below.

Explanation:

I'm considering e as a variable.

As We have c = e/-4,

We can Write this as

c/e = -1/4 [Dividing both sides by e]

As c/e is equal to a constant, we can say c prop e or, c and e are in

direct variation.

But, This results in a confusing situation.

If we take c = 1, we get, e = -4.

But if we put c = 2, we get, e = -8.

So, Actually, If we increase c, e is decreasing, and again, with the same ratio, -1/4.

So, Defintion of Variation and The Results we are getting are contradicting each other.

But still, The graph of the relation shows it is direct.

graph{y = (x/(-4)) [-10, 10, -5, 5]}

I don't think this is a variation. But This is my opinion. I need consultations.

A constant thus neither

Explanation:

e is a constant e~~2.71828.... ->2.72 to 2 decimal places

Thus e/(-4) is also a constant
