    A straight the makes an angle of \[{{135}^{o}}\]with the x-axis and cuts y-axis at a distance -5 from the origin. The equation of the line is [MP PET 1998]

    A) \[2x+y+5=0\]                        

    B) \[x+2y+3=0\]

    C) \[x+y+5=0\]                           

    D) \[x+y+3=0\]

    Correct Answer: C

    Solution :

    \[\because y=mx+c\] Þ \[y=(\tan {{135}^{o}})x-5\]                 Þ \[y=-x-5\Rightarrow x+y+5=0\].
