What does the equation Y=Kx/z indicate about the relationship between variables?

The equation Y = Kx/z illustrates the relationship between the variables by defining how Y changes in relation to x and z. In this equation, K represents a constant.

To understand the relationship better, consider the expression Y = K(x/z). Here, when x increases, assuming K and z remain constant, Y will increase. This indicates a direct variation between Y and x: as x goes up, Y goes up. Conversely, when z increases, Y will decrease if x remains constant, illustrating an inverse relationship: as z goes up, Y goes down.

Thus, the equation encapsulates that Y varies directly with x and inversely with z, making the choice accurate.
