Answer:
y = 69 billion dollars for the year 2000
Step-by-step explanation:
Imports from a certain country grew from about 45 billion dollars in 1994 to 69 billion in 2000
Let
x = year
y = imports
From the given information we have,
(x₁, y₁) = (1994, 45)
(x₂, y₂) = (2000, 69)
The equation of line is given by
(y - y₁) = m(x - x₁)
Where m is the slope and is given by
m = (y₂ - y₁)/(x₂ - x₁)
m = (69 - 45)/(2000 - 1994)
m = 24/6
m = 4
So the equation becomes
(y - 45) = 4(x - 1994)
Estimate the imports for the year 2000.
Substitute x = 2000
(y - 45) = 4(2000 - 1994)
(y - 45) = 4(6)
y - 45 = 24
y = 24 + 45
y = 69 billion dollars
Note:
Since the imports for the year 2000 was already given let us figure out imports for some other year.
Estimate the imports for the year 1997.
Substitute x = 1997
(y - 45) = 4(1997 - 1994)
y - 45 = 4(3)
y - 45 = 12
y = 12 + 45
y = 57 billion dollars
