Solve the problem.
-Assume that the sales of a certain appliance dealer are approximated by a linear function. Suppose that sales were $\$ 7000$ in 1982 and $\$ 76,500$ in 1987. Let $x=0$ represent 1982 . Find the equation giving yearly sales $y$.
A) $S(x)=69,500 x+76,500$
B) $S(x)=13,900 x+76,500$
C) $S(x)=13,900 x+7000$
D) $S(x)=69,500 x+7000$

To find the equation of the line, we first calculate the slope (m) using the given sales values for 1982 and 1987. The change in sales is $76,500 - 7,000 = 69,500$ over 5 years (1987 - 1982). So, the slope $m = 69,500 / 5 = 13,900$. Using the point (0, 7000) for $x=0$ and $y=7000$ (representing 1982), the equation is $y = 13,900x + 7000$.
