Question 201498: Assume that the sales of a certain appliance dealer are approximated by a linear function. Suppose that sales were $4500 in 1982 and $69500 in 1987. Let x = 0 represent 1982. Find the equation giving yearly sales S(x)
possible answers
S(x)=650000x+69500
S(x)=650000x+4500
S(x)=13000x+4500
S(x)=13000x+69500 Answer by solver91311(24713) (Show Source):
If 1982 is 0, then 1987 = 5, so your two points are (0,4500) and (5,69500). Use the two-point form of the equation of a line to write your function where and are the coordinates of the given points.
