1. **State the problem:** Solve for the slope and intercept of the equation $$3y - 3y = -9$$. 2. **Simplify the equation:** Notice that $$3y - 3y = 0$$, so the equation becomes: $$0 = -9$$ 3. **Analyze the equation:** The statement $$0 = -9$$ is false, which means there is no solution to this equation. 4. **Conclusion:** Since the equation is inconsistent, it does not represent a line, so there is no slope or intercept to find.
