    Complete question :

    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
