#### Explanation:

In general, when two lines

The given equation of the line

is in slope-intercept form

where

and

This means that the slope of the line is

Hence, the slope of the line perpendicular to the given line is

To get the y-intercept, simply substitute the coordinate of the point which we know is on the line

Hence, the equation of the line is
