Simple question

1) Just a little nagging problem in the back of my head.
To turn the equation y=2x+1 into y=-2x+1, what would you do?
I said flip it over the y axis? true?

Actually I never watch Star Wars and not interested in it anyway, but I choose a Yoda card as my avatar in honor of our great friend bobbym who has passed away.
May his adventurous soul rest in peace at heaven.

Re: Simple question

Yes. You're mapping
