Q : 11 A line perpendicular to the line segment joining the points and divides it in the ratio . Find the equation of the line.
Co-ordinates of point which divide line segment joining the points and in the ratio is
Let the slope of the perpendicular line is m
And Slope of line segment joining the points and is
Now, slope of perpendicular line is
Now, equation of line passing through point and with slope m is
equation of line passing through point and with slope is
Therefore, equation of line is
