1. ## Urgent help regarding sketching on the r^3 and r^4 planes and in the (v,b) plane.

Hey good day everyone,this is my first post here,so I am sorry if I am not following the proper guidelines for posting here.

The following sets of points represent simple geometric figures in a plane.V and B are real numbers.For each problem draw a sketch in the (V,B) plane and a second sketch in the R^2,R^3,R^4 as appropriate.For each problem identify the geometric shape.

a) S={x:x= (0,1) +V(1,2) + B(2,3) for 0<=V<=1,0<=B<=1}
b) S={x:x= V(2,1,-2) + B(4,-2,3) for 0<=V<=6, 0<=B<=V}
c) S={x:x= V(2,1,-2,2) + B(4,-2,3,-1) for 0<=V<=6, 0<=V<=B}

This is first year first semester algebra in my algebra course,and honestly I have no idea how to go about sketching the two diagrams,if someone could break down as to how these should be down in detail,it would be of great help.

POSTED IN WRONG SECTION,this is UNIVERSITY LEVEL,MOVED THE POST TO UNIVERSITY HELP FORUMS.SORRY.
