Question

For the inverse variation equation Xy = k what is the constant of variation, k, when X = -2 and y =5

Answer 1

The constant of variation is: -10

Step-by-step explanation:

The inverse proportion between y and x is given by:

y ∝ 1/x

When the proportionality symbol is removed, the proportionality consatnt is introduced

So

$y = \frac{k}{x}\\k = xy$

Putting the values of x and y

x = -2

y = 5

$k = -2 * 5\\k = -10$

Hence,

The constant of variation is: -10
