Y = a + bx
The graph and accompanying table shown here display 12
observations of a pair of variables (x, y).

The variables x and y are positively correlated, with a correlation
coefficient of r=0.97.

You estimate the slope of the least squares regression line, y= a + bx,
for these data values to be b = 2. What is the y-intercept, a, of the
least squares regression line? Round your answer to the nearest
tenth.

hope this !

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
