from (1):
(3)
Substituting (3) in (2):
(4)
Isolating
:
(5)
(6)
(7)
Substituting (7) in (1):
(8)
Isolating
:
(9)

-3/2
perpendicular slopes are those that are opposite sign and reciprocal of the original given slope
1/10x200
= 1/10x200/1
= 200/10
=20
the answer is 20
if u dont understand, 1/10 means a part of 200 that is divided by 10 which means the number x10 =200. So if u dont understand, you can check answer this way: n*10=200
200/10=n
n= 20
True.
Let's say that you have two pieces of paper that both represent planes. If you cross them, you'll be able to see that the intersection of these two pieces of paper is a line.
