When asked to write a point-slope equation for a line passing through the points (-2, -2) and (2, 1), a student wrote y - 1 = -3/4(x - 2). how can she fix this to write the correct equation? a - that is the correct equation, no changes are necessary. b - change the sign of the slope. c - distribute -3/4 to each term in parentheses. d - change the minus signs to plus signs. i think it's b, me out a bit. (-3/4 is the slope, it's saying remove the negative sign).

Apoll is being conducted at a mall nothingto obtain a sample of the population of an entire country. what is the frame for this type of​ sampling? who would be excluded from the survey and how might this affect the results of the​ survey? what is the frame for this type of​ sampling? a. the frame is people who need new clothes. b. the frame is people who shop at the mall. c. the frame is people who like to shop. d. the frame is the entire population of the country. who would be excluded from the survey and how might this affect the results of the​ survey? a. any person that does not need new clothes is excluded. this could result in sampling bias due to undercoverage. b. any person who does not shop at the mall is excluded. this could result in sampling bias due to undercoverage. c. any person who does not shop at the mall is excluded. this could result in nonresponse bias due to people not participating in the poll. d. there is nobody that is being excluded from the survey.
