□ 0 spaces
□ \\(\frac{1}{2}\\) spaces
rewatch

Explanation:

Step1: Define distance from zero

The distance of a number from zero is its absolute value, defined as $|x| =

$$\begin{cases} x & x\geq0 \\ -x & x<0 \end{cases}$$

$

Step2: Calculate absolute value of -2

For $x=-2$, apply the absolute value rule:
$|-2| = -(-2) = 2$

Answer:

A. 2 spaces
