There are two kinds of lines (solid line is flexible / does not need to be linear and the dashed line is forced to be linear) shown on the figure to represent the relationship between students' post-test score (post) and the pre-test score (pre).

Question:

From this scatterplot and the two lines, does it appear the relationship is predominantly linear?

Group of answer choices:

No the relationship is not lienar, the solid lines diverges greatly from the dashed line.

Yes the relationship is mostly linear, as the two lines are similar.
