8. A company manufactures and sells video games. A survey of video game stores indicated that at a price of $71 each, the demand would be 200 games, and at a price of $31 each, the demand would be 600 games. If a linear relationship between price and demand exists, which of the following equations models the price-demand relationship?

(Let x represent the price per video game and y represent the demand.)

@Coolsector all I need is that formula you gave me earlier

we have two "points" (71,200) , (31,600)

so the slope m is given by (600-200) / (31-71) = -10
using y=y1+m(x-x1)
we get

y = 200 -10x +710
y = -10x + 910
