    I'm trying to graph: x^2 + y^2 + z^2 = 1, z>0. But I don't know the right syntax to do it :(

    Also, how do I graph the intersection of x = 3, y = 2 ?

    Did you even try? You need a 3D graph and then you need your equation in the form z(x,y). Think about what it means to take the square root of a real number and that should tell you what you need to know about your z>0 constraint.

    Not sure you can graph x = 3 in grapher. Check the Help.
