\[Уравнение\ обратной\ \]
\[пропорциональности:\]
\[y = \frac{k}{x}.\]
\[P(7; - 6):\]
\[- 6 = \frac{k}{7}\]
\[k = - 42.\]
\[E(14;3):\]
\[3 = \frac{k}{14}\]
\[k = 42.\]
\[F\left( - \frac{1}{5};210 \right):\]
\[210 = k\ :\left( - \frac{1}{5} \right)\]
\[k = 210 \cdot \left( - \frac{1}{5} \right) = - 42.\]
\[K\left( 7\frac{1}{2}; - 5\frac{3}{5} \right):\]
\[- 5\frac{3}{5} = k\ :7\frac{1}{2}\]
\[k = 7\frac{1}{2} \cdot \left( - 5\frac{3}{5} \right)\]
\[k = - \frac{15}{2} \cdot \frac{28}{5} = - 3 \cdot 14 = - 42.\]
\[M(14\ ;28):\]
\[28 = \frac{k}{14}\]
\[k = 28 \cdot 14\]
\[k = 392.\]
\[Ответ:точки\ \ P;F;K.\]
