Write the equation of a line parallel to the line:
y=-x-4
that goes through the point (-9,8)

y=-x-1 or, y-8=-1(x+9)

Step-by-step explanation:

Parallel lines have the same slope. in your current equation you have a slope of -1. We can use this slope and your set of points in the point slope formula.

y-y1=m(x-x1)

(-9, 8)

x1 y1 m=-1

y-8=-1(x+9)

y-8=-1x-9

+8 +8

y=-x-1

i used to know how to do this in 7th but i forget easily

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
