To determine the equation of the line of fit from the given options, we need some context or data points that these lines might be fitting. Assuming you have a dataset in mind, the line of fit represents the best linear approximation of that data.
Given the four options:
- \( y = 5x + 70 \)
- \( y = 5x + 80 \)
- \( y = 10x + 70 \)
- \( y = 10x + 80 \)
Without specific data points or further information, we cannot definitively establish which of these equations is the line of fit.
If you have specific data points or can provide additional context (like a scatter plot), we can help you find the best fit line using methods such as least squares regression.
Please provide more details for a precise determination!
