Maria solved the equation -5 n = -9 . her answer was n = 1 . she is fairly confident about her answer, but wants to do a quick check of her solution using estimation.

which of the following shows a good check of her answer?

-6(2) = -12
-5(-2) = -10
-5(2) = -9
-5(2) = -10

-5(2) = -9

Step-by-step explanation:

I think I'm right.. Let me know if I am or if I'm not please :)
