Question

How do you write direct variation equations given y = 32 when x = 8?

Answer 1

`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.
