So this is two x minus y. So it's gonna be two times one minus two, which is equal to zero. And so if the derivative there is equal to zero, then if I were to draw a line that indicates the slope at that point, well, I would draw a line with a zero slope. So it would look something like, let me draw it a little bit. It would look something like that. All right, let's keep going. Let's look at this point, where x is equal to zero, y is equal to two.
