Welcome to Physics Forums.

For the direction with acceleration (vertical, in the case of projectile motion), the equations are the same as the 1-D equations for constant acceleration. Just be aware that the velocity can be expressed as either vy or v·sinθ.

For the direction without acceleration, it is motion with a constant velocity and there is really just one equation, $\Delta x \ = \ v_x \ \Delta t$. An alternative form of the same equation is to express the velocity component as v·cosθ.

Hope that helps.
