\[\boxed{\text{856\ (856).\ }\text{Еуроки\ -\ ДЗ\ без\ мороки}}\]

\[1)\ y(6) = \frac{1}{3} \cdot 6 = 2\]

\[y( - 3) = \frac{1}{3} \cdot ( - 3) = - 1\]

\[y( - 3,2) = \frac{1}{3} \cdot ( - 3,2) = - \frac{16}{15} =\]

\[= - 1\frac{1}{15}\]

\[2)\ при\ y = - 2:\ \ \]

\[\frac{1}{3}x = - 2\]

\[x = \frac{- 2 \cdot 3}{1}\ \]

\[x = - 6.\ \]

\[при\ y = \frac{1}{3}:\ \ \]

\[\frac{1}{3}x = \frac{1}{3}\text{\ \ }\]

\[x = 1.\]

\[при\ y = 12:\ \ \]

\[\frac{1}{3}x = 12\ \ \]

\[x = \frac{12 \cdot 3}{1}\text{\ \ }\]

\[x = 36.\]
