Question

Line A is perpendicular to Line B.

If the slope of Line A is 3
what is the slope of Line B?

Answer 1

Let slope of that line be m

We know product of slopes of two perpendicular line=-1

• 3m=-1
• m=-1/3

Answer 2

- 1/3

Explanation:

m = slope of a line

Perpindicular slope = - 1/m

= - 1/3
