Al the plumber charges $50 to make a house call. He then charges $25 per hour. Write an equation in slope intercept form that shows how much Al would charge for a plumbing job (without charging for parts).

Answer 1

Let y be the total amount charged by Al for a plumbing job and x be the number of hours worked. The equation in slope-intercept form would be:

y = 25x + 50
