Okay, so your equation is:
$\large\color{black}{  y=12x  }$
we can fill in the table for x and y.
(we know that to obtain the y, we have to multiply the x, times 2.
So if x was for example 1, then y is 12.)

The y in this case represents the earnings, per each week x.
 $\normalsize\color{ black }{\LARGE{\bbox[5pt, lightyellow ,border:2px solid  white  ]{ \huge{ \begin{array}{| l | c | r |}
\hline \scr~~~x~~  & \scr f(x)  \
\hline
\scr~~~0~  &  \scr 0    \
\hline
\scr~~~1~  &  \scr 12    \
\hline
\scr~~~2~  &  \scr 24    \
\hline
\scr~~~3~  &  \scr 36    \
\hline
\scr~~~4~  &  \scr 48    \
\hline
\scr~~~5~ & \scr 60     \
\hline   \end{array} }}}}$   (this is a chart for $\large\color{black}{  y=12x  }$ )
so, your "proportion is 12.
