Question:

The graph below was created with Stat Crunch using data from the U. S. Department of Commerce website: (www.commerce.gov). The blue dots on the graph show the percentage of all spending on electronics in the United States that was done online for the years 2010-2017. The red line can be used to approximate this same spending. On the graph, x = 0 represents the year 2010, x = 1 represents the year 2011, x = 2 represents the year 2012, and so on.

Percentage of online Electronics Spending 35- 30 25 E 20 15 10 1 3 4 5 6 Year After 2010 Percenta ge 2.

a) Use the points 10, 202 and 17, 34.72 to calculate the slope of the red line.

b) Determine the equation of the red line.

c) Using the equation you determined in part (b), estimate the percentage in 2016.

d) Using the equation you determined in part (b), determine the year in which the percentage was 24.
