For the inverse variation equation xy = k, what is the constant of variation, k, when x = –2 and y = 5?

-10.

Step-by-step explanation: We are given the inverse variation equation xy = k

We need to find the value of the constant of variation, k for given values x = -2 and y=5.

In order to find the value of the constant of variation, k we need to plug the values of x and y in given  inverse variation equation xy = k and solve for k.

Plugging x=-2 and y =5, we get

xy = k   => (-2) (5) = k.

On multiplying -2 and 5, we get -10.

Therefore, k = -10.

hi,

i'm 75% sure the answer is 1,1 to both lines.

have a great day
