Answer:
Q1. m=8
Q2. Divide by -5
Q3. It's being divided by 5
Q4. It is being multiplied by -5
Answer:
y=2/1x +5
Step-by-step explanation:
m represents the slope of the line on the graph, m would be 2/1.
b represents the point on the y axis the line interects at, b would be 5.

Answer:
E is not a subspace of 
Step-by-step explanation:
E is not a subspace of
In order to see this, we must find two points (a,b), (c,d) in E such that (a,b) + (c,d) is not in E.
Consider
(a,b) = (1,1)
(c,d) = (-1,-1)
It is easy to see that both (a,b) and (c,d) are in E since 1*1>0 and (1-)*(-1)>0.
But (a,b) + (c,d) = (1-1, 1-1) = (0,0)
and (0,0) is not in E.
By the way, it can be proved that in any vector space all sub spaces must have the vector zero.
