ANSWER

The constant of variation is

EXPLANATION.

The constant of variation is the slope connect any two pairs of points.

Recall that the slope formula is given by,



For instance using the points will give the slope to be,





Therefore the constant of variation is


The correct answer is C.

That is so true, i can’t believe how true this is
