  • question_answer
    Slope of a line which cuts intercepts of equal lengths on the axes is                                  [MP PET 1986]o00000

    A)            - 1  

    B)            0

    C)            2     

    D)            \[\sqrt{3}\]

    Correct Answer: A

    Solution :

               The equation of line \[\frac{x}{a}+\frac{y}{a}=1\]Þ \[x+y-a=0\]                    \ \[\text{Slope}=-\frac{\text{Coefficient}\,\text{of}\,x}{\text{Coefficient}\,\text{of}\,y}=-1\].
