Question

The scatter plot shows the annual profit for a certain airline​ (in millions of​ dollars) for years between 2000 and 2010. The equation of the trend line shown is y=0.4x+5.3​, where x represents the number of years since 2000 and y represents the profit. Use the equation to estimate the profit in 200.

Answer 1

The profit made in 2002 is 6.1 million dollars .

Using the linear regression equation given :

• y = 0.4x + 5.3

The number of years since 2000 = x

For , 2002 ; x = 2002 - 2000 = 2

Substitute x = 2 into the equation:

y = 0.4(2) + 5.3

y = 0.8 + 5.3

y = 6.1

The profit made in 2002 is 6.1 million dollars .
