#y = 4 xx x#.

Explanation:

A “direct variation equation” is a relationship between two values. This can usually be represented by a line.

In this case a direct relationship between the two values given could be #y = 4 xx x#.

This equation not only results in the given pair of values, but any other direct variation of y with respect to x. For example, if x is 2, y would be 8.
