Omitted variable bias from a covariance and a variance

The true model is $y = 1 \cdot x_1 + 2 x_2 + \varepsilon$ with $\varepsilon$ exogenous. You omit $x_2$ and regress $y$ on $x_1$. You are told $\operatorname{Cov}(x_1, x_2) = 6$ and $\operatorname{Var}(x_1) = 3$.

Compute what the $x_1$ coefficient converges to and the bias.
