Choose a quotient map $p:\mathbb{Re}_K \rightarrow Y$, where $\mathbb{Re}_K$ denotes the real line in the K-topology and Y be the quotient space obtained from $\mathbb{Re}_K$ by collapsing the set K to a point.

$\mathbb{Re}_K$ is Hausdorff, but Y is not Hausdorff since p(K) and p(0) in Y cannot be separated by disjoint open sets.
