I believe the answer is -6.3
my explanation is because -6.3 is less than -6.1 so technically it makes it smaller. if you were to add to -6.3 you would get -6.1 on the x axis.
        
             
        
        
        
The length of the KN is 4.4
Step-by-step explanation:
We know from Pythagoras theorem  
In a right angle ΔLMN  
Base² + perpendicular² = hypotenuse
²
From the properties of triangle we also know that altitudes are ⊥ on the sides they fall.
 Hence ∠LKM = ∠NKM = 90
°
Given values-
LM=12
LK=10
Let KN be “s”
⇒LN= LK + KN
⇒LN= 10+x        eq 1
Coming to the Δ LKM
⇒LK²+MK²= LM²
⇒MK²= 12²-10²
⇒MK²= 44           eq 2
Now in Δ MKN
⇒MK²+ KN²= MN²
⇒44+s²= MN²       eq 3
In Δ LMN
⇒LM²+MN²= LN²
Using the values of MN² and LN² from the previous equations
⇒12² + 44+s²= (10+s)
²
⇒144+44+s²= 100+s²+20s
⇒188+s²= 100+s²+20s    cancelling the common term “s²”
⇒20s= 188-100
∴ s= 4.4
Hence the value of KN is 4.4
