a line of best fit emphasizes the overall trend shown by all the data taken as a whole :DDD
Yes but phrased differently
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.
It emphasizes the overall trend of the data

The line of best fit does not necessarily have to start from 0. It depends on the data and the model being used. In some cases, the intercept (where the line crosses the y-axis) can be a meaningful value, and in those cases, the line may not start from 0.
Yes but phrased differently
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
A best fit line is used to summarize the relationship between two variables by minimizing the overall distance between the line and the data points. It helps to visually represent trends and make predictions based on the data.
The line of best fit does not have to pass through the 0 (origin) and rarely does
Finding the line of best fit is called linear regression.
