Answer:
The slope between the two points (12,6) and (20,22) is 2.
Step-by-step explanation:
Given : Two points (12,6) and (20,22)
We have to find the slope between the two points (12,6) and (20,22).
Given two points (12,6) and (20,22)
Slope between two points is given by

Here, 
Substitute, we have,

Simplify, we have,
m = 2
Thus, The slope between the two points (12,6) and (20,22) is 2.
