4/10 is equal to 2/5 because if you reduce 4/10 you get 2/5 which shows that they are equal.
You would plug in 6 where the x is so it would be -4 times 2 plus 5(6)
Alright, lets get started.
Please take a look to the diagram I have attached.

We could day it as angle ONM also.
So, the answer is ∠ N and ∠ONM. : Answer
Hope it will help :)
