    If 3, 4 are intercepts of a line \[L=0,\]then the distance of \[L=0\]from the origin is

    A)  5 unit        

    B)  12 unit

    C)  \[\frac{5}{12}\]unit       

    D)  \[\frac{12}{5}\]unit

    Correct Answer: D

    Solution :

    Given, 3, 4 are intercepts of a line. \[\therefore \] Equation of line is \[\frac{x}{3}+\frac{y}{4}=1\] \[\Rightarrow \] \[4x+3y-12=0\] Now,  distance from origin is \[\left| \frac{4\times 0+3\times 0-12}{\sqrt{{{3}^{2}}+{{4}^{2}}}} \right|=\frac{12}{5}\,unit\]
