Which proportion can be used to show that the slope of MP is equal to the slope of PR ?
(8.4A, SS, RCZ)
F
-3+3 63
-2 + 6 -6-2
G
-2-6-6-(-3)
6 (2)
H
|-2-6--6-(-3)
-6-(-2) -3-3
J
-3-3-6-(-3)
-2-6-6-(-2)

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
