# Interpretation of ANCOVA interaction term

I have some doubts in how to interpret the interaction term in an ANCOVA using R since in other statistical programs this term is not provided. If I am right, one assumption of ANCOVA is the Homogeneity of regression slopes (that is, they must be parallel). Not following this assumption means you cannot use ANCOVA.

My question is, can the interaction term be interpreted as a test for the homogeneity of regression slopes? I meant, if is significance is because the slopes are not parallel and the model cannot be ran. If not, how can I test for it?

Here is an example

Thanks,
