What is the slope of the line perpendicular to the line passing through points (2, 3) and (-1, 5)?

✓ Correct Answer: Option D

The slope of the line passing through (2,3) and (-1,5) is (5-3)/(-1-2) = 2/(-3) = -2/3. The slope of a perpendicular line is the negative reciprocal, which is -1/(-2/3) = 3/2.
