    ...
    You need to eliminate either x or y so you end up with a quadratic equation. Then think about when this quadratic has a single solution.

    I recommend starting by rearranging the second equation to give y=1+\frac{k}{2}x then substitute for y in the first equation.

    Try this and post your working if you get stuck.
