Given a positive x value, find a y value in a table of values for lines in the form ax + by = c \begin{tabular}{|l|l|l|c|c|c|}
\hline\( x \) & \( 0 \) & \( 1 \) & \( 2 \) & \( 3 \) & \( 4 \) \\
\hline\( y \) & \( 4 \) &  \( \ \) & \(\color{gold}\bigstar\)
\end{tabular}

This is a table of values for \( x+2 y=8 \) What should replace the star? \( 6 \)
