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. Take the cube root of both sides, you get y minus 1 is equal to 3. Add 1 to both sides, you get y is equal to 4. So we really want to figure out the slope at the point 1, 1, 4, which is right over here.
