Math Example: Estimating the Line of Best Fit: Example 1
This is part of a set of math examples for approximating the line of best fit. The methodology works like this:
1. Calculate the mean of the x-coordinates and the y-coordinates.
2. Graph this point, knowing that this is a point on the actual line of best fit.
3. Based on a visual analysis of the graph, estimate the slope of the line of best fit.
4. Use the Point-Slope Form to find the equation of this estimated line of best fit.
