Explanation:
Given lines
their respective slopes
In the given equation, we have
Transform the equation to slope-intercept form to get the slope.
Now, the equation of the perpendicular line will be something like
To get the y-intercept, simply substitute the coordinates of the point which we know to lie on the line
Hence, the equation of the perpendicular line is
or, in standard form
