Suppose that y varies inversely with x. write an equation for the inverse variation. y = 6 when x = 1/3

Y='x'xk
6=1/3xk
K=18
Y='x'x18
Y=18x

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
