Answer 2

A number line going from negative 1.6 to positive 1.6. An arrow goes from 0 to negative 0.8

Explanation:

Since -0.8 is located to the left of origin so when adding any value it will cause it to shift to the right. For example, add 0.1 to 0.8, we get a value of 0.7 shifting the arrow to the right, same goes for 0.2

-0.8 + 0.1 = -0.7

-0.8 + 0.2 = -0.6

-0.8 + 0.4 = -0.4

-0.8 + 0.6 = -0.2

In this way it ends at -0.2
