Part B Interpret the slope and \( y \)-intercept. The slope is about -2.5 . This means that Mia makes about fewer mistakes each hour she practices. The \( y \)-intercept is about 11 . This means Mia will make about__ mistakes if she practices O hours.

Mia’s journey as a budding musician shows that with every hour she devotes to practice, she sharpens her skills, reducing her mistakes by approximately 2.5. This implies that she's on a path to improvement, proving that practice really does make perfect! The \( y \)-intercept being around 11 hints at the starting point of her learning curve. If Mia puts in zero hours of practice, she can expect to have about 11 mistakes initially. It's like starting a game with a little hiccup, but every hour she plays, she’s fine-tuning her performance!
