Answer is D) Y. It's matching with the results given
0.007, also known as the thousandths place in decimals.
The formula of a midpoint SR:

We have
S(4, 1) and M(7, -5)
Substitute:

<h3>Answer: R(10, -11)</h3>
Okay. So in order to solve this problem, we really have to try out each answer and divide it by 9. A is not correct, because it does not divide evenly. B works, but let's check the others. C and D do not work, but E also works as well. If you can have two answers, 504 and 882 are both exactly divisible by 9. The answers are B: 504 and E: 882.
