4) The table represents a proportional relationship. Find the constant of proportionality and write an equation to represent the relationship. a у 2 2 -1 3 3 1 10 who 12 4 Constant of proportionality Equation:

Answer 1

From the given table, we can see that the ratio of x value and corresponding y value is 3.

herefore, x and y are in Direct proportion.

The proportional constant is 3.

Since

`\begin{gathered} (x)/(y)=3 \\ x=3y \end{gathered}`

So, the relation between x and y is

`x=3y`
