In problem 1 - 3, find the slope of the tangent line to the graph at the point (X1, Y1). 1. Y = 9 - X^2 - 2X1

2. Y = 2X^2 + 4X - 4X1 + 4

3. Y = X^3 + 1

You move the constant to the right side and change its sign to be 9z= -6 -8. that’s the first step.the second step would be calculate the difference of -8-6 to get -14. you equation should now be 9z=-14the last step is to divide both sides by 9 to get z=-14/9hope this
