  • question_answer
    The line joining the points (-1, 3) and (4, -2) will pass through the point (p, q) if

    A) \[p-q=1\]                                  

    B) \[p+q=1\]

    C) \[p-q=2\]                                  

    D) \[p+q=2\]

    Correct Answer: D

    Solution :

               Line joining point \[(-1,3)\]and \[(4,-2)\]is                    \[(y+1)=\frac{-5}{5}(x-3)\] Þ \[y+1=-1(x-3)\]                                                 \[x+y=2\]                              ..... (i)                    If line (i) passes through point (p, q), then \[p+q=2\].
