Question

What does Direct & Inverse variation mean?

Answer 1

Answer: In direct variation, as one number increases, so does the other. This is also called direct proportion: they're the same thing. ... In inverse variation, it's exactly the opposite: as one number increases, the other decreases. This is also called inverse proportion.

Step-by-step explanation:

Answer 2

Step-by-step explanation: Direct variation is the relationship between two variables such that the variables have a constant ratio, k, were k ≠ 0.

If we call our variables a and b, we can use the

following formulas to represent direct variation.

$\frac{a}{b} = k$ or $b = ka$

Inverse variation is also a relationship between two variables but the difference is that as one variable increases, the other variable decreases.

Suppose that our variables are g and h.

As g increases, h will decrease or as g decreases, y will increase.
