. The linear equation represents an estimate of the average cost of a pound of ground beef for year x starting in 2000. The year 2000 would be represented by x=1 since it is the first year of the study. Similarly, 2005 would be year 6, or x=6.3(a) (1 pt) What year would be represented by x=9?

2008

anonymous · Answer

Year 1 = 2000
Year 2 = 2001
Year 3 = 2002
....
....
Year 6 = 2005
Year 7 = 2006
Year 8 = 2007
Year 9 = 2008

) What x-value represents the year 2020?

anonymous · Answer

It seems the answer would be 21 since year 1 is 2000.

anonymous · Answer

3(c) (1 pt) What is the slope (or rate of change) for this equation?
3(d) (1 pt) What is the y-intercept for this equation?

anonymous · Answer

Slope is 1 because the value changes one for one.

y-intercept has to be the year where value of x = 0. That will be year 1999.
