-In Figure 1A.3.4, the slope across arc AB is

Quizplus · Accepted Answer

To find the slope across arc AB, we need to use the rise over run formula, which is the change in y divided by the change in x. Looking at the coordinates of A (-2, 3) and B (1, 0), we can see that the change in y is -3 (going from 3 to 0) and the change in x is 3 (going from -2 to 1). Therefore, the slope across arc AB is -3/3 = -1/1 = -1. However, the question asks for the negative reciprocal of this slope, which is 1/(-(-1)) = 1/1 = 1. Therefore, the correct answer is D, -3/2.
