Step 1.1

Move the limit inside the absolute value signs.

$\frac{| lim_{x \to 8} x - 8 |}{x - 8}$

Step 1.2

Split the limit using the Sum of Limits Rule on the limit as $x$ approaches $8$ .

$\frac{| lim_{x \to 8} x - lim_{x \to 8} 8 |}{x - 8}$

Step 1.3

Evaluate the limit of $8$ which is constant as $x$ approaches $8$ .

$\frac{| lim_{x \to 8} x - 1 \cdot 8 |}{x - 8}$

Step 2

Evaluate the limit of $x$ by plugging in $8$ for $x$ .

$\frac{| 8 - 1 \cdot 8 |}{x - 8}$

Step 3.1.1

Multiply $- 1$ by $8$ .

$\frac{| 8 - 8 |}{x - 8}$

Step 3.1.2

Subtract $8$ from $8$ .

$\frac{| 0 |}{x - 8}$

Step 3.1.3

The absolute value is the distance between a number and zero. The distance between $0$ and $0$ is $0$ .

$\frac{0}{x - 8}$

Step 3.2

Divide $0$ by $x - 8$ .

$0$
