For the inverse variation equation xy=k what is the constant of variation k when x=-3 And y=-2

ELEN [110]

ANSWER

The constant of variation is 6.

EXPLANATION

The inverse variation equation is:

$xy = k$

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

We substitute the values for x and y to get,

$- 3 \times - 2 = k$

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

This implies that;

$k= 6$

Hence the constant of variation is 6.
