Answer:
-10 is the correct answer to the given question .
Step-by-step explanation:
Missing information:
Following question is incomplete there is no information about the vertices and the rules .Following are the complete question that is mention below
Triangle PQR has vertices It is translated according to the rule
. What is the y-value of P'?
Now coming to the solution as already mention in the question
The translated rule is
Now calculated the vertices P value according to the rule of translated
So -10 is the value of y in P vertices .
