18. what is the slope of a line perpendicular to y=1/3x - 2

The slop of line perpendicular to line y = x - 2 is     ( - 3)  

Step-by-step explanation:

Given Line equation as ,

y = x - 2

The equation of line is y = mx + c

Slop of this line (m1) =

Now second line with slop (m2) is perpendicular to line first , then

(m1) × (m2) = - 1

So, (m2) =

Or , (m2) =

∴     (m2) = - 3

Hence the slop of line perpendicular to line y = x - 2 is      ( - 3)      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
