A line perpendicular to the in segment joining the points (1,0) and (2,3) divides it in the ratio `1: n` . Find the equation of the line.

Explanation

According to the section formula, the coordinates of the points that divides the line segment joining the points `(1,0)` and `(2,3) `in the ratio` 1: n` is given by `{frac{{n}(1)+1(2)}{1+{n}}`,

`frac{{n}(0)+1(3)}{1+{n}}}={frac{{n}+2}{{n}+1}, frac{3}{{n}+1}}`

The slope of the line joining the points `(1,0)` and `(2,3`) is` {m}=frac{3-0}{2-1}=3`.

We know that two non-vertical lines are perpendicular to each other if and only if their slpoes are negative reciprocals of each other.



Therefore, slope of the line that is perpendicular to the line joining the points `(1,0)` and` (2,3)` is =-`frac{1}{{~m}}=-frac{1}{3}`
