Quizplus · Accepted Answer

The slope of a straight line is the ratio of the change in the y-coordinate (vertical change) to the change in the x-coordinate (horizontal change) between any two points on the line. Therefore, option B, which compares the absolute vertical change to the absolute horizontal change between two points on the line, is the correct choice.
