With these sums, we can then compute SSxy, which is the sum of the products of x and y minus the product of the sums of x and y divided by n. Similarly, we calculate SSxx, which is the sum of x squared minus the square of the sum of x divided by n.

Using SSxy and SSxx, we can determine the slope of the line, β1, by dividing SSxy by SSxx.
