1. The problem involves understanding the vertical line along the y-axis from -5 to -10. 2. A vertical line along the y-axis means the x-coordinate is constant, specifically $x=0$. 3. The y-values range from $-5$ to $-10$, so the line segment includes all points $(0, y)$ where $-10 \leq y \leq -5$. 4. The equation of this vertical line is simply: $$x=0$$ 5. This line does not depend on $y$, so it extends vertically between the given y-values. 6. The graph description matches the equation $x=0$ with $y$ between $-10$ and $-5$. 7. Therefore, the answer is the vertical line $x=0$ between $y=-10$ and $y=-5$.
