Given that y varies inversely as x, then they follow the next formula:


y=(k)/(x)

where k is some constant.

Substituting with x = 4, and y = 2, and solving for k:


\begin{gathered} 2=(k)/(4) \\ 2\cdot4=k \\ 8=k \end{gathered}

Substituting k = 8 into the general formula, the equation describing the relationship between x and y is:


y=(8)/(x)
