Solve the problem.If Marco hired a plumber for 5 hours the total cost would be $170. If he hired the same plumber for 13 hours , the total cost would be $410. Assume a linear relationship between the cost, y, in dollars and the number of hours worked, x. Find an equation in slope-intercept form that models the relationship between the cost and the number of hours worked.
