Inclined plane and kinetic energy

[marnold1987]

if a block of mass m is to slide up an inclined plane to at least a height of h (with no friction), what is the minimum kinetic energy it must have?

no numbers are included...just supposed to know an equation to get the answer.

Use energy Conservation!
Gravitational Potential energy gained= Initial Kinetic Energy

Equations are just "tools" of physics. More than "just knowing an equation" what physical concepts are involved here? That should help you think of an equation.
