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
