What’s the equation of the blue line?

x + 2y = 4

Step-by-step explanation:

Line is passing through the points (4,0) and (0, 2)

Slope of line (m) = (2 - 0)/(0-4) = 2/(-4) = - 1/2

y - intercept (b) = 2

Equation of line in slope intercept form is given as:

y = mx + b

Plugging m = - 1/2 and b = 2 in the above equation, we find:

answer: 2/4

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
