Question

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

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​
