Question

Which rule represents an inverse variation?

a. y= x^2

b. y= x/k

c. y= k ⋅ x

d. y ⋅x = k

Answer 1

option C. and D.

Explanation:

For two quantities with inverse variation, as one quantity increases, the other quantity decreases. For example, when you travel to a particular location, as your speed increases, the time it takes to arrive at that location decreases.An inverse variation can be represented by the equation xy=k or y=kx .
