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

$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

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.  

is should be y = 5x
