Answer:
C. 2/3
Explanation:
To find the slope of a line from two points, use this formula.

The variable 'm' means slope in algebra.
y² means the second y-coordinate and y^1 means the first y-coordinate.
Based on the previous definition, it should be easy to figure out what x² and x^1 mean.


Therefore, the slope of the line passing through the points (2,4) and (5,6) is 2/3.
