Interpret the linear equation.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 number of miles the car is towed increases 40 miles for every dollar spent on the service. b = 3; The tow truck will tow the car 3 miles for no cost. B. m = 40; The cost of the service increases $40 every mile the car is towed. b = 3; The cost of the service is $3 if the car is not towed. C. m = 3; The cost of the service increases $3 every mile the car is towed. b = 40; The cost of the service is $40 if the car is not towed. D. m = 3; The number of miles the car is towed increases 3 miles for every dollar spent on the service. b = 40; The tow truck will tow the car 40 miles for no cost.
