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 I . Note that this value is not necessarily the middle value shown on the x-axis. (Report one decimal place.) Now propose a line with an intercept of 4.7 that also goes through the point (@, y) - (Report one decimal place.)
