I have been working on a worksheet for my Algebra I class, and I have figured out all but a few problems relating to one question. Help is much appreciated.

A construction company charges $15 per hour for debris removal, plus a one-time fee for use of a trash dumpster. The total fee for 9 hours of service is $195.

Part a)

Write the point-slope form of an equation to find the total feeyfor any number of hours?

part b)

Write the equation in slope-intercept form.

part c)

What is the fee for the use of a trash dumpster?

Thank-you for your time.
