It is, we've got a mini drum roll here, y is equal to negative 16t plus 91. That's the equation of that tangent line right over there. And then they say, we want to use this equation to approximate the internal temperature of the potato at time t equals three. So let's say that this is time t equals three right over here. We want to approximate the temperature that this model describes right over here, but we're gonna do it using the line. So we're gonna evaluate the line at t equals three. So then we would get, let's see, negative 16 times three plus 91 is equal to, this is negative 48 plus 91 is equal to, what is that, 43.
