Solve the problem.In 1990 the number of factory pollution incidents reported in Country X was 7500. This number had decreased roughly at a rate of 440 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 8250 incidents.
A. y = -440(x - 1988) + 7500; 1986 B. y = -440(x - 1982) + 7500; 1980 C. y = -440(x - 1990) + 7500; 1988 D. y = -7500(x - 1990) + 440; 1983
