st-line

Question: The length of perpendicular drawn from origin on the line joining $({x}',{y}')$ and $({x}'',{y}'')$, is


1) $\frac{x'y''+x''y'}{\sqrt{{{(x''-x')}^{2}}+{{(y''-y')}^{2}}}}$
2) $\frac{x'y''-x''y'}{\sqrt{{{(x''-x')}^{2}}+{{(y''-y')}^{2}}}}$
3) $\frac{x'x''+y'y''}{\sqrt{{{(x''+x')}^{2}}+{{(y''+y')}^{2}}}}$
4) $\frac{x'x''+y'y''}{\sqrt{{{(x''-x')}^{2}}+{{(y''-y')}^{2}}}}$
Solution: Explanation: No Explanation
Distance between two lines Perpendicular distance of the line from a point Position of point w.r.t. line
