If the 10 books are all different, we have:
• 10 ways of selecting the first book,
,
• 9 ways of selecting the second book,
,
• 8 ways of selecting the third book,
,
• 7 ways of selecting the fourth book.
The total number of ways to arrange 4 of the 10 books is:
Answer
There are 5040 ways of arranging the books.
12x11=?
Multiply then that is your answer

The second one would prove they are parallel. This is because it uses angles touching both of the parallel lines and uses correct Angle Properties
(3,-1)(4,3)
slope(m) = (3 - (-1) / (4 - 3) = 4/1 = 4
y = mx + b
slope(m) = 4
use either of ur sets of points....(4,3)...x = 4 and y = 3
now sub and find b, the y int
3 = 4(4) + b
3 = 16 + b
3 - 16 = b
-13 = b
so ur equation is : y= 4x - 13 <==
