b. 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 ($\bar{x}$, $\bar{y}$), the sample means of the x and y variables.
The value of $\bar{y}$ is the intercept of the initial blue line. Estimate, by inspection, the value of $\bar{x}$. Note that this value is not necessarily the middle value shown on the x-axis. (Report one decimal place.)
Answer is complete but not entirely correct.
7.5
Now propose a line with an intercept of -0.2 that also goes through the point ($\bar{x}$, $\bar{y}$). (Report one decimal place.)
y = + * x
