Sales Data Analysis and Linear Functions

The video tutorial explains how to analyze sales data for a local retailer over several years. It begins by identifying sales figures for 2013 and then examines the annual increase in sales. The tutorial demonstrates how to model this data using a linear function, with a focus on determining the slope and intercept. Finally, it uses the linear model to predict sales for the year 2018.

What were the sales in the year 2013 according to the table?

• $37,000

• $30,000

• $23,000

• $16,000

By how much did the sales increase each year?

• $8,000

• $6,000

• $5,000

• $7,000

What is the form of the linear function used to model the sales data?

• F(x) = mx + b

• S(x) = mx + b

• G(x) = mx + b

• H(x) = mx + b

What is the slope of the linear function that models the sales data?

• 5

• 8

• 7

• 6

What is the vertical intercept of the linear function?

• 16

• 23

• 30

• 9

If X is 1, what is the corresponding sales value in the table?

• $23,000

• $9,000

• $30,000

• $16,000

How do you calculate the X value for the year 2018?

• Subtract 2010 from 2018

• Add 2010 to 2018

• Multiply 2010 by 2018

• Divide 2018 by 2010

What is the predicted sales value for the year 2018?

• $65,000

• $63,000

• $72,000

• $56,000

What is the base year used for calculating X values?

• 2008

• 2009

• 2010

• 2011

What is the unit of sales in the table?

• Dollars

• Millions of dollars

• Thousands of dollars

• Billions of dollars
