Question

Graph the following expression on the number line by placing the dot in the proper locations. | x | = 2

Answer 1

x = 2

x = -2

Explanation:

The absolute value of x is the distance from the point x to 0.

Given:

|x| = 2

This means you have to find such points, the distances from which to 0 is equal to 2.

There are two such points: 2 and -2. They are symmetric about 0 (lies on the same distance from 0).

The attached diagram shows the positions of these two points.
