To determine the equation of the trend line in a scatter plot, you would typically look at the graphical representation of the data to see which equation best fits the points. However, since I don't have access to the actual scatter plot to analyze it, I cannot definitively identify the correct trend line equation from the given options.
If you have data points or more context about the scatter plot's characteristics (like slope or direction of fit), please provide that information, and I can help you determine which equation might be the best fit. Otherwise, I recommend plotting the equations against the data points to see which one passes through or closely follows the trend of the data in the scatter plot.
