Which of the following is not a correct name for the line above?
here are the answers you can choose from:
ij
kn
kj
ki

Kn

Step-by-step explanation:

Kn is not a correct name for the line given in the diagram as line segment is bounded by the two different points, it includes the both end points.

In the given figure, point "n" is outside the arrows and thus cannot be joined with K in order to form  a line. Whereas, IJ, KJ and KI are the correct lines as they are lying inside the arrows and are joined together to form a line.

x is variable or an unknown value to find

example:

2x = 5 which means x = 3

this "question" looks more like a project is there any other info you can give me about this. it could be too complex for someone else to do on this website
