Tell us what’s happening:
I finished my code.

but I get this error on a test when I run the code.

I can’t understand why my code failed this test and how to fix it. Can anybody help me, I would be grateful.

Did you solve this one already?

I forked and ran your replit and it passed the tests OK

If you still have an error, it might be because your chart doesn’t project the first line of best fit into the future, 1880-2050
