Description: Sal solves a problem where he has to estimate the line of best fit for a scatter plot. Created by Sal Khan. So let's see, we have a bunch of data points, and we want to find a line that at least shows the trend in the data. And this one seems a little difficult because if we ignore these three points down here, maybe we could do a line that looks something like this. And if we ignored these two points right over, we could do something like maybe something like that.
