Denise measures the height of a sunflower every 
other week over a three-month period and records the 
results in the following table.
 
   Weeks.           Height 
      1.                     3.00            
      3.                    4.70
      5.                    6.40
      7.                     8.10
      9.                     9.80
      11.                    11.50
      13.                    13.20
 Denise creates an equation that will allow her to predict 
the height of the sunflower in the future, where x is the 
week and y is the height. Which of the following gives the 
correct equation?
A. Y = 0.85x + 2.15 
B. Y= 1.7x + 2.15 
C. Y = 0.85x + 1.3 
D. Y = 1.7x + 1.3
