What is the absolute value of point b labelled on the number line?

My solution for this is as follows:

First, I have to find the unit of interval. Since there are 5 spaces between the integers, each space would be:

1 - 0 = 5x
x = 0.2
Each interval is equivalent to 0.2. 

Now, point B is 3 spaces from -1 to the left. Thus, its value should be:

B = -1 - 0.2(3) = -1.6
The absolute value is always the positive value. Thus, the positive value of point B is 1.6.
