The slope of the line in simplified form is 
Step-by-step explanation:
The slope of a line which contains points
and 
is 
The given is:
1. Point (-12 , -60) lies on the line
2. Point (60 , -42) lies on the line
We need to find the slope of the line
∵
= (-12 , -60)
∵
= (60 , -42)
- Substitute these values in the rule
∴ 
∴ 
∴ 
∴ 
The slope of the line in simplified form is
