Suppose A and B are points on the number line. If AB = 8 and B lies at −7, where could A be located? Select ALL that apply.
−1
1
15
−15

The correct answers are: 1 and -15

Step-by-step explanation:

Let a be a point on number line and b be the second point on number line.

The distance between two numbers on number line is calculate by subtracting the smaller number from larger number.

Here

AB = 8

B = -7

We have to look at the options one by one.

For A = -1

As A>B

For A = 1

As A>B so

So with A = 1 , AB = 8

This is one of the right answers.

For A=15

As A>B

For A=-15

As B>A

As with A=1 and A=-15, the distance between AB is 8 so these are the correct answers.

Hence,

The correct answers are: 1 and -15
