And so y is equal to one when x is equal to negative one plus b. And so we have one is equal to negative 1 4th plus b. You add 1 4th to both sides, you get b is equal to, we could either write it as 1 1 4th, which is equal to 5 4ths, which is equal to 1.25. We could write it any of those ways. So the equation for the line tangent to the curve at this point is y is equal to, our slope is 1 4th, x plus, and I could write it in any of these ways. I'll write it as plus five over four. And we're done, at least with that part of the problem.
