Final answer:
The question pertains to finding the correct equation for a trend line on a scatter plot in Mathematics. The student is given multiple options, but based on the reference material provided, none of the student's options match the correct equation of y = −3204 + 1.662x.
Step-by-step explanation:
The subject of this question is Mathematics, specifically focusing on scatter plots and linear regression. The student needs to identify which option correctly represents the equation of the trend line for a given scatter plot. To determine the equation for the trend line, one would typically use a calculator's regression function to find the equation of the least-squares regression line after entering the data and creating a scatter plot.
The correct format of a regression equation is usually y = a + bx, where 'a' is the y-intercept and 'b' is the slope of the line. Drawing the line on the scatter plot and finding the slope and y-intercept are key steps in interpreting the relationship between the variables.
In this case, based on the information provided with the reference Solution 12.13, none of the given options (a, b, c, d) match the correct equation of the line of best fit which is y = −3204 + 1.662x. None of the student's provided options have both the correct slope and y-intercept, and thus all of them are incorrect. It's important to review the scatter plot, calculate the correct least-squares line, and ensure the equation is accurately represented.
