    [SOLVED] Three-dimensional coordinate systems

    give a geometric description of the set of points whose coordinates satisy the given inequalities

    x^2 + y^2 <= 1, z = 0


    so here is what i did but i am not sure if this is right or wrong.
    if you set x = 0, y <= 1, and if you set y = 0 , x<=1

    so would the coordinates be (1,1,0) ??
    i have feeling this is not correct.

    all the points on or inside a circle of radius 1 centered at the origin, lying on the x-y plane.

    ah so its more of a bunch of points then 1 point. i think i get it thanks.
