So we know that the point negative one comma, we could just input it right over here, f of negative one is negative 1 1.5, one over negative one minus one, negative 1 1.5. So we know that this negative one comma negative 1 1.5, that that is on our curve and it is on our line, that's the point at which the tangent and the curve actually intersect. And so we can use any of these to now write the equation of our line. We could say y, I'll do it right here, y minus y one, so minus negative 1 1.5 is going to be equal to, is going to be equal to our slope, negative 1 4th, I'm just using the point slope version of our equation, is equal to our slope times x minus x one. So x minus our x coordinate that we know sits on this. So minus negative one. And so let me now write all of this in a neutral color.
