Question 332374: I would appreciate help for this problem! I have tried everything!!
To replace a set of brakes, an auto mechanic charges $60 for parts plus $40 per hour for labor.
The total cost, y, is given by the equation y = 40x + 60, where x is the number of hours of labor.
(a) Identify and (b) interpret the meaning of both the slope and the y-intercept.

The y-axis is the cost, and the x-axis is the # of hours labor.
============================================
The y-intercept is the "base cost" or $60 for parts.
The slope is 40, and is the $ per hour for labor.
