1. **State the problem:** We are given two linear equations:
$$y = \frac{5}{9}x - 1$$
and
$$y = -\frac{1}{9}x - 7$$
We want to find the point where these two lines intersect.
2. **Set the equations equal to find the intersection:** At the intersection point, both $y$ values are equal, so:
$$\frac{5}{9}x - 1 = -\frac{1}{9}x - 7$$
3. **Solve for $x$:** Add $\frac{1}{9}x$ to both sides:
$$\frac{5}{9}x + \frac{1}{9}x - 1 = -7$$
Simplify the left side:
$$\frac{6}{9}x - 1 = -7$$
Which simplifies to:
$$\frac{2}{3}x - 1 = -7$$
Add 1 to both sides:
$$\frac{2}{3}x = -7 + 1$$
$$\frac{2}{3}x = -6$$
Divide both sides by $\frac{2}{3}$:
$$x = \frac{-6}{\cancel{\frac{2}{3}}} \times \cancel{\frac{3}{2}}$$
Since dividing by $\frac{2}{3}$ is the same as multiplying by $\frac{3}{2}$:
$$x = -6 \times \frac{3}{2}$$
$$x = -9$$
4. **Find $y$ by substituting $x = -9$ into one of the original equations:** Using the first equation:
$$y = \frac{5}{9}(-9) - 1$$
$$y = -5 - 1$$
$$y = -6$$
5. **Final answer:** The lines intersect at the point $$\boxed{(-9, -6)}$$.
