The percent of adults who smoke, recorded every few years since 1967, suggests a negative linear association with no outliers. A line was fit to the data to model the relationship.

Which of these linear equations best describes the given model?

Choose 1 answer:

(Choice A)

A

y=-0.5x+40

(Choice B)

B

y=-x+40

(Choice C)

C

y=-2x+40

(Choice D)

D

y=-3x+40



Based on this equation, estimate what percent of adults smoked in 1997.

Round your answer to the nearest tenth of a percent.
