Answer: The second description is correct for the absolute value of x
Main details: Horizontal line from 0 to the dot 6 ticks to the left, and 6 written above the line
Step-by-step explanation: breaking it down:
A number line is shown from negative 6 to positive 6 with increments of 1. All the numbers are labeled on the number line. The first part is the same in all of the descriptions
<u>A dot is shown on a point at 6 tick marks to the left of 0. </u> <em>This represents -6 on the number line. </em>
Above the number line, a bracket is shown <u>extending from a point at 6 tick marks to the left of zero to 0.</u><u> </u> This shows the distance between 0 and -6. Important. Absolute value is the distance between two numbers
A horizontal line is shown between the brackets, <em>This is the measuring line 6 units long.</em>
<u> and 6 is written on the line.</u><u> </u> Important. It is a plain number, no negative or positive! Absolute value is just that.
