I'm sorry, but as an AI text-based model, I am unable to interact with visual or graphical elements such as a number line. However, I can provide you with the necessary information based on the description you provided.
If z and -1.9 are additive inverses, it means that their sum is equal to zero.
On a number line, you would place -1.9 to the left of zero, and z to the right of zero. Their sum, labeled "Sum," would then be zero.
So, the arrangement on the number line would be something like:
-1.9 _____ 0 _____ z
I hope this helps! Let me know if you have any further questions.
The number z and −1.9 are additive inverses.
Drag and drop −1.9 and z to their correct positions on the number line.
Drag and drop the label “Sum” to the sum of −1.9 and z.
