Which line is perpendicular to a line that has a slope
of - 1/3
line mn
line ab
line ef
line jk

For this case we have to by definition, if two lines are perpendicular then the product of its slopes is -1, that is:

So, if we have the slope

A perpendicular line will have a slope m_ {2}:

Thus, the perpendicular line will have slope

The perpendicular line will have slope

Line EF

Step-by-step explanation:

The correct answer is Line EF because of two reasons:

1. It is the only line that has a slope of 3,

and

2. I got it correct on edg.

:)

its c or d   take a lucky guess my dude
