Answer 1

y is 3 times more than x
does this give you an idea of what the answer should be?

Answer 2

\(\bf \begin{array}{cccllll}
\textit{something }&\textit{varies directly to }&\textit{something else}\\ \quad \\
\textit{something }&={\color{red}{ \textit{some value }}}&\textit{something else}\\ \quad \\
y&={\color{red}{ n}}&x&\implies y={\color{red}{ n}}x
\end{array}\\ \quad \\
y=12\qquad x=4\qquad \implies 12={\color{red}{ n}}4\)

solve for "n", or the "constant of variation"

once you found that, plug it back in the equation

Answer 3

y=kx

12=k(4)

Solving for k would give you your function.
