The following set of ordered pairs represents a power inverse variation. (2,4),(1,32),(4,1/2)
what is the value of r

the kind of function they're looking for is y=k/x^r
I've gotten this far
4=k/2^2=r
but I can't figure out how to get k or r without having the other one first

What does independent variable and dependent variable mean in math?

Pls yall i really need the answer fr fr
