Geometry

Question Analysis:
This question tests understanding of slope calculation between two points in a quadrilateral.
The focus is on proper application of the slope formula.

Key Concept Explanation:
Slope measures the steepness of a line, calculated as the ratio of vertical change to horizontal change between two points.

Step-by-Step Solution:
For points N(3, 5) and O(6, 4):
Slope = (4 - 5)/(6 - 3) = (-1)/3 = -1/3

Common Mistakes:
Students frequently swap x and y differences or mishandle negative signs in slo...
