its called a trendline
Forcing the trendline through the origin when analyzing data is a decision that depends on the context of the data and the specific analysis being conducted. In some cases, it may be appropriate to force the trendline through the origin if there is a theoretical reason to believe that the relationship between the variables being analyzed should pass through the origin. However, in other cases, it may be more appropriate to allow the trendline to be freely fitted to the data without forcing it through the origin. Ultimately, the decision to force the trendline through the origin should be based on the specific goals of the analysis and the underlying assumptions about the relationship between the variables.
