What is the equation of the line containing the points (3,1), (9,3) and (27,9)

y = (1/3)x

Step-by-step explanation:

If this is truly a line, then we can find its equation using any two of the three given points.  If we go from (3, 1) to (27, 9), x increases by 24 and y increases by 8.  Thus, the slope of this line is m = rise / run = 8 / 24, or m = 1/3.

Using the point (3, 1) and the slope m = 1/3, the slope-intercept form y = mx + b becomes 1 = (1/3)(3) + b.  Thus, b = 0, and the line is y = (1/3)x.

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
