4 which scatter plot does not show an appropriate line of best fit?

Brief Explanations:

A line of best fit should closely follow the general trend of the data points, with points distributed evenly around it. In option C, the line is too steep and does not align with the downward trend of the plotted points; most points lie far below the line, meaning it fails to represent the data's pattern appropriately. The other options have lines that match their respective positive or negative trends well.

Answer:

C. (The scatter plot with the steep downward line where most points lie far below it)
