Question

Use a single equation or a pair of equations to describe the circle of radius 1 centered at (-3,4,1) and lying in a plane parallel to the yz-plane.

Answer 1

Answer:

describe the given set with a single equation or with a pair of equations

1.) The circle of radius 1 centered at (-3,4,1) and lying in a plane parallel to:

a.) xy-plane

b.) yz-plane

c.) xz-plane

2.) the line through the point (1,3,-1) parallel to the

a.) x-axis

b.) y-axis

c.) z-axis

okay so I answered several other questions similar the part that confuses me here is the parallel part. there were other questions such as : the circle radius 2 centered at (0,0,0) and lying in the xy-plane. Which would be x2+y2=4; z=0.

What confuses me is the parallel part, both here and in more advance problems/chapters. I would be very grateful if someone could explain to me the relevance of this and how it changes the problem, thank you in advance
