1. The problem is to solve the equation $108 \div y = 18$ for $y$. 2. The formula used here is to isolate $y$ by multiplying both sides of the equation by $y$ and then dividing both sides by 18. 3. Starting with the equation: $$108 \div y = 18$$ 4. Multiply both sides by $y$ to get rid of the division: $$108 = 18y$$ 5. Now divide both sides by 18 to solve for $y$: $$y = \frac{108}{18}$$ 6. Simplify the fraction: $$y = \frac{\cancel{108}}{\cancel{18}} = 6$$ 7. Therefore, the solution is $y = 6$. 8. The vertical line segment from 0 to 24 in the graph is unrelated to the solution of this equation. Final answer: $y = 6$
