    Statement-1: The straight line \[2x+3y=4\] intersects the hyperbola \[4{{x}^{2}}-9{{y}^{2}}=36\] in exactly one point.
    Statement-2: The line is parallel to an asymptote of the hyperbola.

    A)  Statement-1 is true, Statement-2 is true; Statement-2 is a correct explanation for Statement-1.

    B)  Statement-1 is true, Statement-2 is true; Statement-2 is not a correct explanation for Statement-1.

    C)  Statement-1 is true, Statement-2 is false.

    D)  Statement-1 is false, Statement-2 is true.

    Correct Answer: A

    Solution :

     The hyperbola is\[\frac{{{x}^{2}}}{9}-\frac{{{y}^{2}}}{4}=1\]. It's asymptotes are \[y=\pm \frac{2}{3}x\]. Clearly the given line is parallel to \[y=-\frac{2}{3}x\], hence intersects the hyperbola at exactly one point.
