Shira's math test included a survey question asking how many hours students spent studying for the test. The scatter plot below shows the relationship between how many hours students spent studying and their score on the test. A line was fit to the data to model the relationship. Which of these linear equations best describes the given model? Choose 1 Choose 1 (Choice A) A \hat y=x+45 y ^ =x+45y, with, hat, on top, equals, x, plus, 45 (Choice B) B \hat y=10x+45 y ^ =10x+45y, with, hat, on top, equals, 10, x, plus, 45 (Choice C) C \hat y=-10x+45 y ^ =β10x+45y, with, hat, on top, equals, minus, 10, x, plus, 45 Based on this equation, estimate the score for a student that spent 555 hours studying.
