Morphology
The meaning is directly compositional: 'regression' (a statistical model showing variable relationships) combined with 'line' (a graphical line) yields a line that represents the regression fitted to data. This follows a standard noun‑noun compound pattern and would be predictable to a learner who knows both constituent words, albeit domain‑specific.
Etymology
Regression line is a straight line drawn through a group of dots on a graph to show the general direction of the dots. It shows the 'relationship' between two things, so the name helps you remember it is the line that shows how one thing changes when the other changes.
