Answer:
The models are different.
Step-by-step explanation:
Yelania and Audrey took two cards which are 4,-6 and 4,6 respectively.
They do not lie on the same points as the sum of Yelania's cards=4-6=-2 and the sum of Audrey's cards=4+6=10.
Both -2 and 10 lie differently on the number line.
Therefore, the models are different from each other.
