Solve the problem.In 1990 the number of factory pollution incidents reported in Country X was 4300. This number had decreased roughly at a rate of 660 per year since 1982. (i) Find an equation of a line 
that describes this data, where y represents the number of pollution incidents during the year x. (Answers may vary.) (ii) Estimate the year when there were approximately 7740 incidents.
A. y = -660(x - 1990) + 4300; 1985 B. y = -660(x - 1982) + 4300; 1977 C. y = -4300(x - 1990) + 660; 1980 D. y = -660(x - 1988) + 4300; 1983
