Solve the problem.Assume that the sales of a computer retail store are approximated by a linear function. Sales were 
in 1984 and 
in 1989. Let x = 0 represent 1984. Find the equation giving yearly sales. Estimate sales in 1992.
A. y = 340,000x + 770,000 y = 3,830,000 in 1992 B. y = 510,000x + 770,000 y = 4,850,000 in 1992 C. y = 408,000x + 770,000 y = 4,034,000 in 1992 D. y = 510,000x + 770,000 y = 4,340,000 in 1992
