Passage
Suppose
W
1
W_1
and
W
2
W_2
are subspaces of
R
3
\mathbb{R}^3
defined as follows:
W
1
=
{
(
0
,
y
,
z
)
∣
y
,
z
∈
R
}
,
W
2
=
{
(
x
,
y
,
z
)
∈
R
3
∣
x
+
y
+
z
=
0
}
,
W_1=\{(0,y,z)\mid y,z\in\mathbb{R}\},\quad W_2=\{(x,y,z)\in\mathbb{R}^3\mid x+y+z=0\},
with usual addition and scalar multiplication. Based on the above data, answer the given subquestions.
