[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.
