C r Since we solved the equation of the sphere for y and took the negative root this is the left half of a sphere. (Sometimes called a hemisphere)

x y z x y z x y z Changing what values that x, y and z are being set equal gives a plane that is parallel to one of the coordinate planes x y z x y z x y z Lines in 3 Dimensions A line in 3 dimensions is described using 3 equations each giving the x, y and z coordinates on the line with an independent variable called a parameter.
