How would these two lines be different?
y= 3x - 10
y= 30r - 10

the first equation would start at -10 on a graph, and go up 3 over 1. For the second equation it would still start at -10, but go up 30 over 1. The slope of equation 1 -s 3, the slope of equation 2 is 30. That is how they are different.

Step-by-step explanation:

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
