Your goal with this tool is to find the "line of best fit" that minimizes the "sum of squared residuals." This "best" line will always go through the point (@, y) , the sample means of the x and y variables. The value of y is the intercept of the initial blue line. Estimate, by inspection, the value of a . Note that this value is not necessarily the middle value shown on the x-axis. (Report one decimal place.) Provide an equation for ANY alternative line that also goes through the point (@, y) . (Report one decimal place.) x Answer is complete but not entirely correct. * 11 5 0.0 1+ 3.0 X X
