Question

For the inverse variation equation xy = k, what is the constant of variation, k, when x = –3 and y = –2?

A) -6

B) -2/3

C) 3/2

D) 6

Answer 1

D) 6

xy = k

-3 * -2 = 6

Answer 2

Answer: Option D) 6

Solution:

xy=k

What is the constant of variation: k=?

when x=-3 and y=-2

Replacing the knwon values in the given equation:

xy=k; x=-3, y=-2

(-3)(-2)=k

Multiplying the values:

6=k

k=6
