a- Give an example equation of each of thecommon surfaces in this course (plane, sphere, cylinder, cone,paraboloid) and describe feature(s) that distinguish its graph fromthe others.
b- If you want to determine an equation of a line thatpasses through the point (0,0,1) and that is parallel to thexy-plane, how many such lines are possible and what do they allhave in common? Give equations of at least twoDIFFERENT such lines are part of yourresponse.
