# Constant variance in this ambiguous residual versus fits plot?

I obtained the following residual versus fits plot using R:

Does this plot obey the simple linear regression assumption of constant variance? I think it doesn't since the residuals seem to get more dispersed as the 'fits' values increase, but I am hoping that I can get a second opinion on this somewhat ambiguous graph. Are there any additional graphs that I can draw in R to determine whether the residuals obey constant variance?

• Seems like your line at about 20 degrees up from horizontal is a more pressing issue ... Sep 4 '20 at 21:24

If possible try and identify the points in the line with a shallow slope that increases with fit, the rightmost of which is the highest residual at approximately at $$3.5x10*5$$
