A survey was done to determine the effect of students changing answers while taking a multiple-choice test on which there is on
ly one correct answer for each question. Some students erase their initial choice and replace it with another. It turned out that 65% of the changes were from incorrect answers to correct and that 29% were from correct to incorrect. What percent of changes were from incorrect to incorrect?
B is correct. Explanation Below: --- Line A never intersects Line B, as they are parallel lines-the slopes are the same-and parallel lines never intersect. Line A's Slope: (9-5)/(-1-1) = -2 Line B's Slope: (-6-2)/(4-0) = -2 --- Hope this helps!
