The scatter plot shows the annual revenue for one airline. The equation of the trend line shown is y = 0.4x + 4.1, where x represents the number of years since 2000 and y represents the revenue in millions of dollars. What was the approximate difference between 2003 and 2007?
The difference in revenue was approximately million ______ dollars
Answer:
$1.6 million
Step-by-step explanation:
Given the trend line equation : y = 0.4x + 4.1
x = years since 2000 ; y = revenue in $ million ;
Approximate difference between 2003 and 2007
In year 2003 ; x = 2003 - 2000 = 3
y = 0.4(3) + 4.1
y = $5.3 million
In year 2007 ; x = 2007 - 2000 = 7
y = 0.4(7) + 4.1
y = $6.9 million
Aproximate difference :
$6.9 million - $5.3 million = $1.6 million
