Question

Is 1/5y=x a direct proportion

Answer 1

Yes --- it is a direction proportion

Constant ---- 1/5

1/5y = x

We are given two variables x and y

`\begin{gathered} (1)/(5)y\text{ = x} \\ if\text{ x is directly proportional to y} \\ x\text{ }\propto\text{ y} \\ x\text{ = ky} \\ \text{Where k is the constant} \\ \text{Therefore, k = }(1)/(5) \\ \end{gathered}`

Theerefore, the function is a direct proportion and the constant is 1/5
