    The equation of a line through the intersection of lines \[x=0\] and \[y=0\]and through the point (2, 2), is  [MP PET 1984]

    A)            \[y=x-1\]                                  

    B)            \[y=-x\]

    C)            \[y=x\]                                      

    D)            \[y=-x+2\]

    Correct Answer: C

    Solution :

               Obviously the point of intersection is (0, 0). Thus the equation of line passing through the points (0, 0) and (2, 2) is \[y=x\].
