Please don't hesitate to give a "thumbs up" in case you're satisfied with the answer
No, the assumption doesn't appear satisfied.
Why not - because we see that variance with respect to yhat is increasing with respect increasing yhat If there is a trend in variance then there a problem of heteroscedasticity
