The correct answer is y = 1.5x, A.
I am sure it is because I took the K12 test. I used the answer from the other person that answered this, and got it wrong. I reviewed the test, and It says that 1.5x is correct.
706,421 rounded to the nearest thousand is 706,000 because the 421 is less than 500 so the 6 would remain a 6.
The answer is 7.
