Is the line through the points P(1, 6) and Q(2, 14) perpendicular to the line through the points
R(4,0) and S(12, -1)? Explain.

understand that i don't know the answers

will someone answer his question

goog may be able to you find that answer

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
