Question

1.)Which two numbers on the number line have an absolute value of 1?

Answer 1

Absolute value is defined as the distance of a number from zero on a number line.

Since, the distance can never be negative, hence, absolute value can never be negative.

For example 1 is 1 away from the origin and -1 is also, 1 away from the origin.

Therefore, absolute value of both -1 and 1 is 1. Mathematically, we can write

|-1| =1

|1|=1

Therefore, the number 1 and -1 on the number line have an absolute value of 1.
