    y≥3x

    Remember, it has to be an inequality so an = sign will not work.

    If you are graphing the inequality:

    The line will be solid since it is ≥ and shade above the line.

    Just graph like a regular y=mx+b slope.

    So draw a point at (0,0) and then go up 3 and right 1, to (1,3) then go up 3 and right 1. Keep repeating this.
