Y= -2x - 14
where y = mx + b
where m is the slope (-2)
and b is the y-value of the y-intercept (-14)
Using a 1-sample z-interval for the population proportion with confidence level 0.997, the sample probability is 0.69 with margin of error of 0.16, so between 0.69+0.16=0.85 of the population and 0.69-0.16=0.53 of the population prefers coffee. 84% and 54% are the correct answers.
