The line of best fit is a straight line that best represents the data on a scatter plot. It should pass through the middle of the data points, showing the general trend.

Step2: Analyze each option

• Option A: The line is horizontal. But the data points show an upward trend, so this is incorrect.
• Option B: The line has a downward slope. But the data points show an upward trend, so this is incorrect.
• Option C: The line is too far from some data points.
• Option D: The line passes through the middle of the data points, showing the upward trend.
