WebCalculates the point at which a line will intersect the y-axis by using existing x-values and y-values. The intercept point is based on a best-fit regression line plotted through the known x-values and known y-values. Use the INTERCEPT function when you want to determine the value of the dependent variable when the independent variable is 0 (zero).

For instance, the point (85.0, 98.6) + had a residual of 7.45, so in the residual plot it is placed at (85.0, 7.45). Creating a residual plot is sort of like tipping the scatterplot over so the regression line is horizontal.

That is: we add up all the numbers xi, and divide by how many there are. But the "mean of x^2" is not the square of the mean of x. We square each value, then add them up, and then divide by how many there are. Let's call it x2bar: x2bar = Σ (xi^2) / n.
