a) what is KN+IKb)What is the coordinate of midpoint GO

Given the figure of a number line
a) We will find the value of KN+IK
As shown in the figure:
[tex]\begin{gathered} K=0 \\ N=3 \\ I=-2 \\ So, \\ KN+IK=0\times3+(-2)\times0=0+0=0 \end{gathered}[/tex]So, the answer will be KN+IK = 0
b) )What is the coordinate of midpoint GO
As shown:
[tex]G=-4,O=4[/tex]The midpoint =
[tex]\frac{-4+4}{2}=\frac{0}{2}=0[/tex]So, the answer will be the midpoint will be k = 0
