Find the Derivative - d/dy -xy

$- x y$

Step 1

Since $- x$ is constant with respect to $y$ , the derivative of $- x y$ with respect to $y$ is $- x \frac{d}{d y} [y]$ .

$- x \frac{d}{d y} [y]$

Step 2

Differentiate using the Power Rule which states that $\frac{d}{d y} [y^{n}]$ is $n y^{n - 1}$ where $n = 1$ .

$- x \cdot 1$

Step 3

Multiply $- 1$ by $1$ .

$- x$
