Chapter 2 - Derivatives - 2.1 Derivatives and Rates of Change - 2.1 Exercises - Page 113: 12

$\frac{dy}{dx}$ = -5

1. Use the product Rule : (First * derivative of second) + (second * derivative of first). 2. First * derivative of second = -5 since the derivative of X is 1 times -5 is -5. 3. Second * derivative of first = 0 since derivative of a constant is 0.
