Question
Find the slope of the line n perpendicular to line h and passing through point P.
- 7
- -1
- -7
Hint:
As we know that when two lines are perpendicular their product would be -1. So to find line n which is perpendicular to h we need to find the slope of h then we will get slope of line n
The correct answer is: 7
The slope of the line h ,m = 
slope of the line n perpendicular to h=
