Ответ:
\[y = - \frac{1}{3}x + 1\]
| \[x\] | \[0\] | \[3\] |
|---|---|---|
| \[y\] | \[1\] | \[0\] |
\[y = - \frac{1}{3}x - 2\]
| \[x\] | \[0\] | \[3\] |
|---|---|---|
| \[y\] | \[- 2\] | \[- 3\] |
\[y = - \frac{1}{3}x\]
| \[x\] | \[0\] | \[3\] |
|---|---|---|
| \[y\] | \[0\] | \[- 1\] |

\[y = - \frac{1}{3}x + 1:\]
\[Ox - (3;0);\ \ Oy - (0;1).\]
\[y = - \frac{1}{3}x - 2:\]
\[Ox - ( - 6;0);\ \ Oy - (0; - 2).\]
\[y = - \frac{1}{3}x:\]
\[Ox - (0;0);\ \ Oy - (0;0).\]
