Question

Find the slope of the line perpendicular to x-3y+5=0

Answer 1

Answer:

This is an easy one...

Step-by-step explanation:

m1m2 = -1 is the condition for two lines to be perpendicular where m1 and m2 are the slopes of the two lines .

Slope of given line , m1 = - ( coefficient of x / coefficient of y )

= - ( 1/-3 )= 1/3

Now using the above condition ; 1/3 × m2 = -1 ; m2 = -3

Hence answer is -3.
