    How to graph this unit step function

    Hello, I need some help graphing this function: U[K]=-KU[-K]
    I know in relation to ramp function U[K]=KU[K] the graph increases by 1 for all values greater than 0 and stays at 0 for anything less than 0. Would the graph be the inverse of the ramp functions graph as it can be related to U[-K]? ive included a picture of my graph.
