The endpoints of a line segment are at the coordinates (–6, 3, 4) and (4, –1, 2). What is the midpoint of the segment?

a
(–1, 1, 3)

b
(–2, 2, 6)

c
(–10, –2, 2)

d
(–5, –1, 1)

Step-by-step explanation:

Use the midpoint formula:

We want to find the midpoint of the line

that has endpoints.

We simplify to get;

This finally gives:

The correct answer is A.

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
