Solve the problem.When a tow truck is called, the cost of the service is given by the linear function 
, where y is in dollars and x is the number of miles the car is towed. Find and interpret the slope and y-intercept of the linear equation.
A. m = 40; The cost of the service increases $40 every mile the car is towed. b = 2; The cost of the service is $2 if the car is not towed. B. m = 2; The number of miles the car is towed increases 2 miles for every dollar spent on the service. b = 40; The tow truck will tow the car 40 miles for no cost. C. m = 40; The number of miles the car is towed increases 40 miles for every dollar spent on the service. b = 2; The tow truck will tow the car 2 miles for no cost. D. m = 2; The cost of the service increases $2 every mile the car is towed. b = 40; The cost of the service is $40 if the car is not towed.
