The answer to your question is:
Step-by-step explanation:
If the line is rotated, we get the perpendicular of the initial line.
See the attachment, the blue line is the original and the red one is the new line.
Process
new slope = 2/5
Point ( 0, 4)
(y - y1) = m (x - x1)
( y - 4) = 2/5 (x - 0)
y - 4 = 2/5 x
y = 2/5 x + 4 New line
We can rewrite the two sets as
So, the first set is composed by all numbers smaller then 3, and the second is composed by all numbers greater than 1.
The intersection of two sets is composed by all the elements appearing in both sets, so
Is the set composed by all number that are less than 3 and more than 1, at the same time.
In other words, you're simply asking
