The line is not a good fit because the points on the residual plot have a clear pattern. This indicates that the linear regression model may not accurately capture the relationship between the variables. The presence of a pattern in the residual plot suggests that the model may be missing important variables or may not be the best choice for the data. Further analysis or a different type of model may be needed for a better fit.
