Perhaps the simplest way to answer this question is to re-run the command in the form lm(Y-X ~ X, Data) and inspect the p-value at the bottom right of the summary output: it is a simultaneous test of your hypotheses.

To test both at the same time, try lm(y~x,offset=x,...) or equivalently lm((y-x)~x,,...) then look a the F-value for the regression. If you just want to test for slope being different from 1, just look at the test for its coefficient.

| Jul 16, 2021 at 10:17 | comment | added | Thomas | Thank you for you comment! So if I understand correctly, my intercept is different from 0, and so is my slope. Could you help me in identifying if my slope is different from 1? Thanks a lot! | |
