So what I want to do is figure out the slope at x is equal to 1. So when x is equal to 1, as you can imagine, once we implicitly take the derivative of this, we're going to have that as a function of x and y. So it will be useful to know what y value we get to when our x is equal to 1. So let's figure that out right now. So when x is equal to 1, our relationship right over here becomes 1 squared, which is just 1, plus y minus 1 to the third power is equal to 28. Subtract 1 from both sides, you get y minus 1 to the third power is equal to 27. It looks like the numbers work out quite neatly for us.
