a) Graph attached below

b) See Below

Step-by-step explanation:

a)

Graph is attached below.

It is a negative sloping line with y-intercept of 0.

b)

The equation of a line is given as

y = mx + c

Where m is the slope (rise/run) and c is the y-intercept (the place where it cuts the y-axis)

Looking at y = -2x, we see that slope is -2 and y-intercept is 0.

The meaning of slope is rise/run, or the change in y/change in x.

So, a slope of -2 can be written as:

It means "for every change in 1 units of x, there is a change (negative) of 2 units in y".

Or we can say for every per unit change in x (positive), the change in y is -2 (negative).

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
