Answer 2

What does "3 units back?"

Answer 3

well it means that how much it goes on one of the axis

Answer 4

yup, hence if x =0 at the beginning, then after "3 units back", what is it now?

Answer 5

sorry my computer crashed for a couple mins

Answer 6

-3

Answer 7

is that right

Answer 8

Yes, but first off, you need reflect all points against xz plane by using formula \(T(x,y, z)= (x,-y,z) \)
For example, for the first point (0,5,4), after reflected against xz plane, what do you have now ?

Answer 9

ok this right
(0, -5, 4)
(-2, -7, 4)
(0, -7, 4)
(0, -7, 6)

Answer 10

yup, now, just pick the first one to do (0,-5,4)
move back x -3
move left y -2
move up, z +4
what do you have?

Answer 11

(-3, -7, 8)

Answer 12

yup, I think so. Do the same with others.

Answer 13

Answer 18

I think so

Answer 19

so what do i do next

Answer 20

Done

Answer 21

but do i say the rule is

Answer 22

as above, -3 for x, -2 for y, +4 for z

Answer 23
