Specifically, what is the value of the slope of the linear trend equation? (Round your answer to 2 decimal places.)
Added by Alexander V.
Step 1
Let \( t \) represent the week number and \( P \) represent the number of passengers. We aim to fit a linear equation of the form: \[ P = a + bt \] where \( a \) is the y-intercept and \( b \) is the slope. Show more…

U.S. Air Travel The number of revenue passengers enplaned in the United States over the 14 -year period from 1994 to 2007 is shown in Table $1.7 .$ Table can not copy (a) Graph a scatter plot of the data. Let $x$ be the number of years since 1994 . (b) From 1994 to 2000 the data seem to follow a linear model. Use the 1994 and 2000 points to find an equation of the line and superimpose the line on the scatter plot. (e) According to the linear model, in what year did the number of passengers seem destined to reach 900 million? (d) What happened to disrupt the linear model?

Modeling and Equation Solving
Solve. Assume each exercise describes a linear relationship. Write the equations in slope-intercept form. See Example 8 . In 2006 , there were 935 thousand eating establishments in the United States. In 1996 , there were 457 thousand eating estab. lishments. (Source: National Restaurant Association) a. Write an equation describing the relationship between time and number of eating establishments. Use ordered pairs of the form (years past 1996, number of eating establishments in thousands). b. Use this equation to predict the number of eating establishments in 2010
