Notice that for every 6 units increment in the x-values in the table, there is a 2 units increment in the y-values.
Therefore, the constant of proportions is:
[tex]\begin{gathered} \frac{2}{6}\rightarrow\frac{1}{3} \\ k=\frac{1}{3} \end{gathered}[/tex]
To find the equation, we'll use this constant as the slope. Using this, point
(6, 2) of the table and the slope-point form:
[tex]\begin{gathered} y-2=\frac{1}{3}(x-6) \\ \rightarrow y-2=\frac{1}{3}x-2 \\ \rightarrow y=\frac{1}{3}x \end{gathered}[/tex]
This way the equation is:
[tex]y=\frac{1}{3}x[/tex]
