A line of best-fit.
Because the "best fit" line is usually required to be a straight line, but the data points are not all on one straight line. (If they were, then the best-fit line would be a real no-brainer.)
Finding the line of best fit is called linear regression.
A best-fit line is the straight line which most accurately represents a set of data/points. It is defined as the line that is the smallest average distance from the data/points. Refer to the related links for an illustration of a best fit line.

It tells you that if there were a linear relationship between the two variables, what that relationship would look like and also how much the observations differed from that linear fit.
The line that minimized the sum of the squares of the diffences of each point from the line is the line of best fit.

What is the difference between a trend line and a line of best fit

As I know, it is like this... From the bottom point you have put, you connect it till the end point with just a straight line. You don't follow every points as that isn't line of best fit. Hope that did help! :)
Oh, honey, let me break it down for you. A trend line is a general direction showing the overall trend of data points, while a line of best fit is a specific line that minimizes the distance between the line and the data points. So basically, a trend line is like a rough sketch, and a line of best fit is like the tailor-made suit that hugs those data points just right.
The line of best fit does not have to pass through the 0 (origin) and rarely does
