\[1)\ \text{A\ }( - 4;\ - 7),:\]
\[\ - 7 = \frac{28}{- 4}\ \]
\[- 7 = - 7 \Longrightarrow проходит.\]
\[2)\ \text{B\ }( - 14;\ - 2),:\]
\[\ - 2 = \frac{28}{14}\]
\[- 2 \neq 2 \Longrightarrow \ не\ проходит.\]
\[3)\ \text{C\ }(0,5;14):\ \ \]
\[14 = \frac{28}{0,5}\ \]
\[14 \neq 56\ \Longrightarrow \ не\ проходит.\]

\[140 = \frac{28}{0,2}\text{\ \ }\]
\[140 = 140\ \Longrightarrow \ проходит.\]
