To derive the equation of the line through the origin based on the provided information, we can use the points given on the graph to identify the relationship between inches (y-axis) and feet (x-axis).
From the points provided:
- When \( x = 1 \), \( y = 12 \)
- When \( x = 2 \), \( y = 24 \)
- When \( x = 3 \), \( y = 36 \)
We can see that for every 1 foot (x increase of 1), the inches (y) increase by 12. Therefore, the ratio of inches to feet is 12 inches for every 1 foot.
This gives us the slope of the line as: \[ \text{slope} = \frac{y}{x} = 12 \]
Thus, the equation of the line can be expressed as: \[ y = 12x \]
So the correct response is: y = 12x
