Sketch a picture of the situation.
Then decompose the initial velocity into its horizontal and vertical components.
Since only gravity is accelerating the particle downwards, the horizontal component has uniform velocity. The vertical component is in freefall.
So you can setup up the value of x and y as a function of t.
