Homework Help: Pre Algebra

Posted by Bill Bob on Wednesday, March 23, 2011 at 12:07am.

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?
