Nia solved the equation -1.98 = 5.2v + 13.1. Her answer was v = -2.9. She is fairly confident about her answer, but wants to do a quick check of her solution using estimation to make sure her answer is reasonable. Which of the following shows a good check of her answer? -2 = 5(-3) + 13 -3 = 5(-2) + 13 -1 = 5(-2) + 13 -2 = 5(-2) + 13
