Answer: 
Step-by-step explanation:
The standard equation of a line in intercept form is given by :-
, where m is the slope of the line. (1)
Given equation of a line : 
It can be written as :

By comparing to the equation (1) , we have

Also, the product of slopes of two perpendicular lines is -1.
Let p be the slope of the line perpendicular to
, then we have

Hence, the slope of the line perpendicular to
=
