is the correct answer and this expression can be simplified to find the slope of the line of best-fit in the scatterplot below by using the the slope equation :

What is Slope of the Line?
The slope of the line is the measure of its steepness and direction. Without using a compass, determining the slope of lines in a coordinate plane can help predict whether the lines are parallel, perpendicular, or none at all.
Any two distinct points on a line can be used to calculate the slope of that line. The slope of a line formula computes the "vertical change" to "horizontal change" ratio between two distinct points on a line. In this article, we will learn about the slope-finding method and its applications.
