Точка: \((7; \frac{26}{11})\)
Уравнение: \(y = kx - 3 - \frac{7}{11}\)
\[\frac{26}{11} = k \cdot 7 - 3 - \frac{7}{11}\]
\[\frac{26}{11} = 7k - \frac{33}{11} - \frac{7}{11}\]
\[\frac{26}{11} = 7k - \frac{40}{11}\]
\[7k = \frac{26}{11} + \frac{40}{11}\]
\[7k = \frac{66}{11}\]
\[7k = 6\]
\[k = \frac{6}{7}\]
Ответ: \(k = \frac{6}{7}\)
