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 = 2; The number of miles the car is towed increases 2 miles for every dollar spent on the service. y-intercept: 80; The tow truck will tow the car 80 miles for no cost. B. m = 2; The cost of the service increases $2 every mile the car is towed. y-intercept: 80; The cost of the service is $80 if the car is not towed. C. m = 80; The number of miles the car is towed increases 80 miles for every dollar spent on the service. y-intercept: 2; The tow truck will tow the car 2 miles for no cost. D. m = 80; The cost of the service increases $80 every mile the car is towed. y-intercept: 2; The cost of the service is $2 if the car is not towed.
