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
