Solve the problem.
-Assume that the sales of a certain appliance dealer are approximated by a linear function. Suppose that sales were $4500 in 1982 and $63,000 in 1987. Let x = 0 represent 1982. Find the equation giving yearly sales S(x).
A) S(x) = 58,500x + 4500
B) S(x) = 11,700x + 4500
C) S(x) = 11,700x + 63,000
D) S(x) = 58,500x + 63,000

Quizplus · Accepted Answer

The slope of the line is calculated as (63000 - 4500) / (1987 - 1982) = 11,700. The equation is S(x) = 11,700x + 4500, where x = 0 represents 1982.
