Question

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

Answer 1

Answer:

The slope of the perpendicular line is -3.  

Step-by-step explanation:

Given : The slope of the line is $\frac{1}{3}$

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 $\frac{1}{3}$

The negative reciprocate of slope is

$\frac{1}{3}$ became -3,

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

Answer 2

My best answer would be -3

hope this helps!
