Question

Lines k and n are perpendicular. If the slope of line k is -6, what is the slope of line n?

A. 6
B. 1/6
C. -6
D. -1/6

Answer 1

For perpendicular lines:
"Their slopes' product is -1"

According to this rule:
the slope of line n is the negative of the reciprocal of the line k's slope


`Slope~of~line~n=-( (1)/(slope~of~line~k) )=- ((1)/( -6 ) )=(1)/( 6 )`

Answer 2

The answer would be B. 1/6
