A line of best-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.
Yes but phrased differently
The line of best fit does not have to start from 0.
What is the difference between a trend line and 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.)
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.
you mean line of best fit?
Finding the line of best fit is called linear regression.
The line of best fit does not have to pass through the 0 (origin) and rarely does
the line of best fit a line that you draw through your graph that divides all of the points on your scatter plot evenly
