Answer: i think its 2
Explanation: because I'm pretty sure, according to my calculations, 1 + 1 = 2 and if you times that by y1 it equals 6 and then you always have to have to had 9 to 6 because ofc mhm fax, and then your answer should be 1.9 and then if you round that to the nearest denominator and then multiply it by the numerator you should get 2. And then you multiply that by 0. Your welcome :). Oh and also if that's not right just put C. You're welcome
