On an airplane flight, Steve watched a display that showed the number of minutes since the flight took off and the number of miles away from the destination. He recorded various points and fit the line
y
=
2
,
426
−
8
x
to the data, where
x
is the number of minutes flying and
y
is the number of miles from the destination. According to the model, how far was Steve from his destination after 120 minutes of flying?
A.
960 miles

B.
1,466 miles

C.
2,410 miles

D.
3,386 miles

Answer 1

Plug x = 120 into y = 2426 − 8x:

y = 2426 − 8(120) = 2426 − 960 = 1466.

So he was 1,466 miles away (choice B).
