Question

How does inverse variation work? (STILL NEEDING HELP)

Answer 1

inverse variation means you have an equation
\[ y = \frac{k}{x} \]
where k is some constant

Answer 2

What is differrent from a normal variation?

Answer 3

direct variation means
\[ y = k x \]

Answer 4

the difference is as x gets bigger in *direct variation* y gets bigger
as x gets bigger in *inverse variation*, y gets smaller.

Answer 5

so I just need a constant of variation that works in division instead?

Answer 6

@phi so to find the value k, I multiply x*y?

Answer 7

If you know you have inverse variation *and* you have an (x,y) pair, then you would use the x, y numbers in the equation
y = k/x
solving for k, we get xy= k or k= x*y

so yes, if you have an (x,y) pair you can find k.
