Interpret the linear equation.The monthly cost of a certain long distance service is given by the linear function 
where y is in dollars and x is the amount of time in minutes called in a month. Find and interpret the slope and y-intercept of the linear equation.
A. m = 0.08; The number of minutes called in a month increases 0.08 for every dollar spent. b = 7.95; The number of minutes that can be called when x = 0 is 7.95. B. m = 7.95; The number of minutes called in a month increases 7.95 for every dollar spent. b = 0.08; The number of minutes that can be called when x = 0 is 0.08. C. m = 7.95; The cost of the long distance service increases $7.95 for every 1 minute called. b = 0.08; The cost of the long distance service is $0.08 if no calls are made for the month. D. m = 0.08; The cost of the long distance service increases $0.08 for every 1 minute called. b = 7.95; The cost of the long distance service is $7.95 if no calls are made for the month.
