Find three solutions of the equation. y = 7x a. (–2, –14), (3, 21), (–4, –28) b. (0, 0), (–3, –23), (–2, –14) c. (3, 21), (0, 0), (–1, –6) d. (–2, –14), (3, 21), (2, 13)

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
