ANSWER

EXPLANATION
The line given to us has equation,

We need to write this equation in the slope intercept form to obtain,


The slope of this line is 

Let the slope of the perpendicular line be 

Then 


This implies that,


Let the equation of the perpendicular line be,

We substitute the slope to get,

Since this line passes through 

it must satisfy its equation.
This means that,




Wherefore the slope-intercept form is
