Graph the following expression on the number line by placing the dot in the proper locations. | x | = 2
1 answer:
Answer:
x = 2
x = -2
Step-by-step 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.

Step-by-step explanation:
Any inequality that does not include the "or equal to" case will be graphed with a dashed line.
<h3>Application</h3>The "or equal to" case is included when the inequality symbol is one of ≤ or ≥. When symbols > or < are used, the boundary line of the solution space is dashed (or the end point on the number line is an open circle).
The inequalities that will be graphed with a dashed line are ...
- 2x -4y < 12 . . . . choice B
- x +7 > -1 . . . . . . .choice D
