Here's the link to the question and graph needed for the questions: https://i.gyazo.com/ae3ab7313df5068060a77e8b74c18443.png

The following graph is a residual plot derived from a scatterplot that predicted the height of girls from their ages (in years).

A. Does the residual plot indicate that a line is a good model for predicting the
height of girls from their ages? Explain.

B: If you were using the regression line to predict the y-value for x = 5.5 years, would your prediction most likely be too large or too small? Explain your Reasoning.

Yes but the line is small, which is the correct answer. My teacher inputted "what about =3" so just saying "The line is small" is incorrect.
