Suppose you have an after school baby sitting service. You charge a flat fee of $10 per week plus $3 per hour. The equation y = 3x + 10 represents your earnings per week for one child.
Describe the y intercept.
Answer: The y intercept is (0,10) but I'm unsure how to describe. I assume no hours were worked (X=0)....but I can't reconcile the $10 charge.
Thoughts?

You're on the right track with your assumption that the y intercept represents the situation where no hours were worked (x=0). In this case, the y intercept is the point (0, 10).
To describe the y intercept, we need to understand what the point (0, 10) represents in the context of the problem. In this scenario, the $10 charge is the flat fee per week, regardless of the number of hours worked. Therefore, when no hours are worked (x=0), the y-value (earnings per week) is $10.
So, when x (hours worked) is zero, the y intercept (earnings per week) is $10. It represents the baseline earning of $10 even if no hours are contributed.
