ANSWER
The constant of variation is 6.
EXPLANATION
The inverse variation equation is:

We want to find the constant of variation, when x=-3 and y=-2.
We substitute the values for x and y to get,

Multiply out the left hand keeping in mind that negative times negative yields a positive result.
This implies that;

Hence the constant of variation is 6.
