The image contains four scatter plots, each displaying a set of data points and a line representing a trend or fit. Below is a detailed description of each plot:### Top Left Plot (Plot a)- **Axes:** The x-axis ranges from 0 to 6, and the y-axis ranges from 0 to 15.- **Data Points:** There are four black data points scattered across the plot.- **Line:** A blue line that is steeply ascending, suggesting a strong positive linear relationship between the variables.### Top Right Plot (Plot b)- **Axes:** The x-axis ranges from 0 to 6, and the y-axis ranges from 0 to 15.- **Data Points:** Four black data points are distributed across the plot.- **Line:** A blue curved line indicating a potential exponential relationship, with the curve rising steeply as x increases.### Bottom Left Plot (Plot c)- **Axes:** The x-axis ranges from 0 to 6, and the y-axis ranges from 0 to 15.- **Data Points:** Four black data points are scattered.- **Line:** A blue line with a positive slope, indicating a moderate positive linear relationship.### Bottom Right Plot (Plot d)- **Axes:** The x-axis ranges from 0 to 6, and the y-axis ranges from 0 to 15.- **Data Points:** Four black data points are distributed.- **Line:** A blue line with a gentle slope, suggesting a weak positive linear relationship.Each plot illustrates different types of relationships (linear and possibly exponential) between the x and y variables, useful for understanding data trends. **Consider the following:**| \( x \) | 1 | 2 | 3 | 4 ||-----|---|---|---|---|| \( y \) | 2 | 6 | 10 | 10 |(a) **Find an equation of the least-squares line for the data. (Round your numerical values to one decimal place.)**\( y = \) [ ] *Check the degree of your polynomial.*[Red "X" indicating an error in the polynomial degree](b) **Draw a scatter diagram for the data and graph the least-squares line.****Graph Analysis:**- **Scatter Diagram (Left Graph):** - Displays a scatter plot with points at coordinates (1, 2), (2, 6), (3, 10), and (4, 10). - A blue line represents the least-squares line, which shows a positive linear trend but does not perfectly fit the points.- **Alternative Graph (Right Graph):** - Shows a different fitting curve, possibly a higher-degree polynomial, which better approximates the scatter data. - The blue curve passes closer to more points, suggesting a better fit than the linear line for this dataset.
