dlaire's math teacher finds that there's roughly a linear relationship between the amount of ime students spend on their homework and their weekly quiz scores. This relationship can de repreeented by the equation \( y=66+6.5 x \), where \( y \) represents the expected quiz scor and s represents hours spent on homework that week. What could the number 65 represent in the equation?

Beyond the Answer
In the equation \( y = 66 + 6.5x \), the number 66 represents the y-intercept. This means that if a student were to spend 0 hours on homework, their expected quiz score would still be 66. It's like a baseline score that reflects the minimum level of understanding a student can achieve just by attending class and picking up a bit of knowledge, even without dedicating any homework time! Now, about that 6.5: it's the slope of the equation, indicating that for every additional hour spent on homework, a student's quiz score is expected to increase by 6.5 points. This catchy number reinforces the idea that investing time into studying can lead to significant improvements in academic performance—pretty motivating, right?
