Question
The image consists of four scatter plots labeled A, B, C, and D. Each plot presents a collection of data points marked by blue dots, along with a red trend line to represent the overall relationship between the variables plotted on the x and y axes. ### A. - **Graph Description**: The scatter plot shows data points scattered with a slight downward trend. The red trend line has a negative slope, indicating a negative correlation between the x and y variables, though the fit is not perfect. ### B. - **Graph Description**: This scatter plot has data points that are more horizontally spread, with the red trend line displaying a very slight downward slope. There's less of a correlation present in this dataset when compared to the others, indicating a weaker linear relationship. ### C. - **Graph Description**: Here, the data points show a clearer downward trend, and the red trend line reflects a steeper negative slope compared to graph A. This suggests a stronger negative correlation than in the previous plots. ### D. - **Graph Description**: The data points continue the downward trend with a pronounced negative correlation, as evidenced by the steep red trend line. Among the graphs, this one indicates the strongest negative linear relationship between the x and y variables. Each graph helps visualize different levels of correlation strength between two variables, using the slope of the trend line as a key indicator.

**Question:** Which of the following best approximates the line of best fit? **Diagram Explanation:** The image depicts a scatter plot with several data points plotted on an X-Y axis. The y-axis is labeled \( y \), and the x-axis is labeled \( x \). The data points show a general downward trend as the values on the x-axis increase. On this scatter plot, a line of best fit should minimize the distances of the data points from the line, showing the overall trend in the data. In this case, the line would likely have a negative slope, indicating a negative correlation between the variables, meaning that as one variable increases, the other tends to decrease.
