Question

Which statement is true if m and n are perpendicular? A slope m = slope (n)B slope m= -1 (Divide) slope (n)C slope m = 1 (Divide) slope (n)D slope m = -1 x slope (n)

Answer 1

The slope of 2 perpendicular lines are negative reciprocals of each other.

In this case:

slope m= -1/n

1/n is the reciprocal, and has a negative sign because is also the negative reciprocal of m.

So. Correct option is

B.slope m= -1 (Divide) slope (n).
