    The equation of line passing through the points of intersection of parabola \[{{x}^{2}}=8y\] and ellipse \[\frac{{{x}^{2}}}{3}+{{y}^{2}}=1\], is  

    A)  \[3y+1=0\]                        

    B)  \[y-3=0\]

    C)  \[y+3=0\]                          

    D)  \[3y-1=0\]

    Correct Answer: D

    Solution :

    We have \[\frac{8y}{3}+{{y}^{2}}=1\Rightarrow (3y-1)(y+3)=0\] \[\therefore y=\frac{1}{3}(\operatorname{Reject}\,\,y=-3)\]
