So it's negative 1 4th x minus 1 4th, minus 1 4th, and then I can subtract 1 1.5 from both sides. So I'm going to get y is equal to negative 1 4th x, and then if I already am subtracting 1 4th and I subtract another half, that's going to be negative 3 4ths. So minus three, minus 3 4ths. So, and that's actually pretty close to what I drew up here. This should be intersecting the y axis at negative 3 4ths. So there you have it. This line, or you could even say this equation, is going to be a very good linear approximation, about as good as you can get for a linear approximation, for that nonlinear function around x equals negative one.
