1. **State the problem:** Kirsten is making gingerbread cookies and needs to convert grams to ounces using the equation $$y = 0.04x$$ where $y$ is ounces and $x$ is grams. 2. **Find three solutions:** Choose three values for $x$ (grams) and find corresponding $y$ (ounces). - For $x=0$: $$y = 0.04 \times 0 = 0$$ - For $x=100$: $$y = 0.04 \times 100 = 4$$ - For $x=200$: $$y = 0.04 \times 200 = 8$$ So, three solutions are $(0,0)$, $(100,4)$, and $(200,8)$. 3. **Draw the graph:** The graph is a straight line passing through these points with $x$ from 0 to 400 and $y$ from 0 to 8. 4. **Interpret negative values:** Negative values of $x$ (grams) do not make sense because grams cannot be negative in this context. Hence, the domain is $x \geq 0$. **Final answer:** Three solutions: $(0,0)$, $(100,4)$, $(200,8)$. Negative $x$ values are not meaningful here.
