Hi. We know that the y coordinates is the same (4). The x is different. So what we have to do first is put negative 4 to absolute value which is 4. Then add the two x coordinates together. Your answer will be 12. I hope this answers your question!
Answer:
12
Step-by-step explanation:
The y is the same (4) so -4 + 12 +8
Hope this helps
