Question

The slope of a line is 1/3. what is the slope of a line perpendicular to this line?

Answer 1

My best answer would be -3

hope this helps!

Answer 2

The slope of the perpendicular line is -3.

Explanation:

Given : The slope of the line is
`(1)/(3)`

To find : What is the slope of a line perpendicular to this line?

Solution :

We know,

When two lines are perpendicular then one slope is negative reciprocate of other slope.

We have given the slope of one line is
`(1)/(3)`

The negative reciprocate of slope is

`(1)/(3)` became -3,

Therefore, The slope of the perpendicular line is -3.
