Quizplus · Accepted Answer

The slope of a curve between two points can be determined by calculating the rise over run between those points. If the slope across an arc from point a to point b is negative, it means the curve is descending as it moves from left to right. Therefore, a slope of -1/2 indicates a moderate decline, making option B the correct choice.
