    The equation of the line passing through (1, 1) and parallel to the line \[2x+3y-7=0\] is                                         [RPET 1996]

    A)            \[2x+3y-5=0\]                        

    B)            \[3x+2y-5=0\]

    C)            \[3x-2y-7=0\]                          

    D)            \[2x+3y+5=0\]

    Correct Answer: A

    Solution :

               Required equation of the line, \[2x+3y+\lambda =0\]                    This line passing through point (1, 1)                    Þ \[2+3+\lambda =0\Rightarrow \lambda =-5\]                    \ Required equation is \[2x+3y-5=0\].
